Slide-A-Lyzer Dialysis cassettes are available in four different sizes to accommodate sample volumes between 0.1 and 30 mL. These devices are easier to use than traditional dialysis tubing, providing both faster buffer exchange and more complete sample recovery. Slide-A-Lyzer Cassettes can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and sample concentration. Liquid samples are easily added and removed by penetrating the self-sealing gasket with a hypodermic needle attached to a syringe. No knots, clips or caps are needed to seal the units and prevent leaking and sample-loss during the dialysis procedure.
Gamma-irradiated Dialysis Cassettes:
Gamma-irradiated Slide-A-Lyzer Dialysis Cassettes are ideal for researchers culturing cells and microorganisms; purifying viruses, DNA and RNA; or performing sample preparation for other applications requiring conditions that minimize the risk of sample contamination. The gamma-irradiated cassettes are treated with 20-36 kGy of gamma radiation, a dosage that has been determined to sterilize the units based on both trypticase soy broth medium for identifying total growth and fluid thioglycollate medium for identifying anaerobic growth. However, a confirmation of sterility is not provided for individual lots, as no further sterility testing is conducted post irradiation.

Slide-A-Lyzer Dialysis Cassettes are constructed from two sheets of low-binding, regenerated-cellulose dialysis membrane that are hermetically sealed on either side of a silicone-like gasket inside an inert plastic frame. The membrane and cassette materials are compatible with most common laboratory chemicals and buffers.

SnakeSkin™ Dialysis Tubing, 3.5K MWCO, 35 mm (Thermo Scientific™)

Thermo Scientific SnakeSkin Dialysis Tubing, 3.5K MWCO, is an easy and ready-to-use form of traditional dialysis membrane tubing that allows desalting and buffer exchange for 10 to 100 mL samples.

Features of SnakeSkin Dialysis Tubing, 3.5K MWCO, 35mm:

Convenient—ready to use, pre-wetted, pleated tube
High recovery—greater than 90% protein recovery
Speed—dialysis is generally completed in 4 to 6 hours
Stability—compatible with a variety of laboratory solutions, including acids, bases, hydrophobic solvents and alcohols

3.5K MWCO Tubing Specifications:
Membrane Type: Regenerated cellulose
Tubing Nominal Dry Thickness: 0.9 to 1.2mil (22 to 30 µM)
Glycerol Content: Trace
Sulfur Content: 0.1% to 0.15%
Heavy Metals Content: Trace

SnakeSkin Dialysis Tubing, 3.5K MWCO, is composed of regenerated-cellulose dialysis tubing and supplied as an open, pleated (telescoped) tube. SnakeSkin Dialysis Tubing is supplied in eight inch (20 cm) sticks containing 35 feet of dialysis tubing having a 16, 22, or 35mm circular internal diameter (I.D.). With similar capacity to 10.5 meters of 23 to 50 diameter dry flat width tubing, the hydrated SnakeSkin Dialysis Tubing holds ~2 to 10 mL of sample per centimeter of length.

The easy-open, pleated format of SnakeSkin Dialysis Tubing was developed to simplify large volume sample dialysis. To use, simply pull out and cut off the required length of tubing, fold over one end of tubing and apply a dialysis clip to close it, add sample at the open end and use a second clip to close the remaining end. Clips are sold separately. In comparison, many traditional dialysis tubing membranes that are supplied as dry, flattened rolls that are difficult to open and often require extensive soaking before they can be used.

The SnakeSkin membrane-pleating process does not change the tubing's MWCO. Also, any low MW contaminants present are removed during the dialysis process. Because SnakeSkin Dialysis Tubing is made from the same type of regenerated cellulose as flat tubing, its dialysis performance matches that of conventional tubing.

Slide-A-Lyzer™ MINI Dialysis Device, 20K MWCO, 0.1 mL (Thermo Scientific™)

Thermo Scientific Slide-A-Lyzer MINI Dialysis Devices, 20K MWCO are disposable polypropylene cups with integrated, low-binding membranes for dialysis and high recovery of proteins and macromolecules >20kDa in volumes from 10 µL to 2 mL.

Features of Slide-A-Lyzer MINI Dialysis Device, 20K MWCO, 2 mL:

Three convenient sizes – dialysis devices for 0.1, 0.5 and 2 mL samples fit standard 1.5 mL-micro centrifuge, 15 mL- and 50 mL-conical tubes, respectively
Excellent sample recoveries – low-binding plastic and small membrane surface area minimize sample loss compared to filtration and resin systems
One-step protocol – pipette sample into the MINI Device and place in tube containing the dialysis buffer; no laborious assembly, device preparation or expensive equipment are required
100% leak-tested – innovative design does not permit "wicking" that can occur in home-made devices
Time savings – performs desalting of nucleic acids and proteins (>95% recovery) in less than 15 minutes, which improves sample resolution, quantification and conjugation

These 20K MWCO dialysis devices are available in three sizes (0.1, 0.5 and 2 mL capacities), and are designed to allow easy sample addition and removal using a standard laboratory pipette. The MINI Devices are effective and convenient for accomplishing typical sample desalting or buffer exchange in 4 to 8 hours. Unlike other small sample separation devices, there is no equipment to assemble, no need for syringe adapters and no laborious steps necessary to manipulate the small volume sample. The regenerated cellulose membrane is compatible with a number of common chemicals and buffers.

Slide-A-Lyzer MINI Dialysis Devices were developed as a convenient means for dialysing small-volume samples of nucleic acids and proteins without undue sample loss. Low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, micro conjugation reactions, and concentration can be accomplished with these devices. Slide-A-Lyzer MINI Dialysis Devices are manufactured in a HEPA filter/clean environment and auto-bagged after assembly to ensure that they are free of contaminants and ready to use.

The 0.5 mL and 2 mL MINI Dialysis Devices fit in and are capped by inserting them into the included 15 mL and 50 mL conical tubes, respectively. The tubes can be securely placed in standard laboratory racks or shakers; this feature saves space, minimizes the risk of spills or contamination, and eliminates the need for floats or large beakers of buffer. Using these MINI Dialysis Devices, low molecular weight contaminant removal, buffer exchange and desalting, can be accomplished within 4 to 8 hours with efficiencies, rates, and recoveries very similar to conventional dialysis using a large dialysate volume (view data).

The 0.1 mL MINI Dialysis Devices are designed to be capped (caps included) and inserted into standard 1.5 mL micro centrifuge tubes. Alternatively, as many as 25 MINI Devices can be placed in a Slide-A-Lyzer MINI Dialysis Device Float for dialysis of multiple inside a large beaker. Using the 0.1 mL MINI Device, 100 µL of pH 2.8 glycine buffer can be equilibrated with 1 liter of pH 9.4 bicarbonate buffer in less than 10 minutes.

As with all dialysis applications, the observed rate of dialysis for each sample used with these devices depends on a variety of factors including membrane to sample volume, temperature and agitation rates; as well as the molecular weight, shape, degree of hydration, and charge of the molecules passing through the membranes and the pH, ionic strength, and solvent characteristic of the buffers being used.

These 10K MWCO dialysis devices are available in three sizes (0.1, 0.5 and 2 mL capacities), and are designed to allow easy sample addition and removal using a standard laboratory pipette. The MINI Devices are effective and convenient for accomplishing typical sample desalting or buffer exchange in 4 to 8 hours. Unlike other small sample separation devices, there is no equipment to assemble, no need for syringe adapters and no laborious steps necessary to manipulate the small volume sample. The regenerated cellulose membrane is compatible with a number of common chemicals and buffers.

Slide-A-Lyzer MINI Dialysis Devices were developed as a convenient means for dialysing small-volume samples of nucleic acids and proteins without undue sample loss. Low molecular weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, micro conjugation reactions, and concentration can be accomplished with these devices. Slide-A-Lyzer MINI Dialysis Devices are manufactured in a HEPA filter/clean environment and auto-bagged after assembly to ensure that they are free of contaminants and ready to use.

The 0.5 mL and 2 mL MINI Dialysis Devices fit in and are capped by inserting them into the included 15 mL and 50 mL conical tubes, respectively. The tubes can be securely placed in standard laboratory racks or shakers; this feature saves space, minimizes the risk of spills or contamination, and eliminates the need for floats or large beakers of buffer. Using these MINI Dialysis Devices, low molecular weight contaminant removal, buffer exchange and desalting, can be accomplished within 4 to 8 hours with efficiencies, rates, and recoveries very similar to conventional dialysis using a large dialysate volume (view data).

The 0.1 mL MINI Dialysis Devices are designed to be capped (caps included) and inserted into standard 1.5 mL micro centrifuge tubes. Alternatively, as many as 25 MINI Devices can be placed in a Slide-A-Lyzer MINI Dialysis Device Float for dialysis of multiple inside a large beaker. Using the 0.1 mL MINI Device, 100 µL of pH 2.8 glycine buffer can be equilibrated with 1 liter of pH 9.4 bicarbonate buffer in less than 10 minutes.

As with all dialysis applications, the observed rate of dialysis for each sample used with these devices depends on a variety of factors including membrane to sample volume, temperature and agitation rates; as well as the molecular weight, shape, degree of hydration, and charge of the molecules passing through the membranes and the pH, ionic strength, and solvent characteristic of the buffers being used.

The Pierce Device for rapid equilibrium dialysis (RED) was developed in association with the pharmaceutical industry to provide the easiest, fastest and most reliable system for performing plasma protein-binding assays.

The RED Device is an apparatus for performing equilibrium dialysis experiments in a high throughput, automation-compatible format, and consists of disposable inserts and a base plate formatted to a standard microplate footprint. It has been extensively validated for plasma-binding assays and produces results consistent with those reported in the literature. The RED Device also offers significant improvements in automation, time requirements, versatility and product reliability compared to other commercially available equilibrium dialysis systems.

Features of the RED Device Inserts:
Each single-use, disposable insert is made of two side-by-side chambers separated by a vertical cylinder of dialysis membrane (in 8K or 12K MWCO) validated for minimal nonspecific binding. This format requires no extensive assembly steps or specialized equipment, and each chamber or well is easily accessible from the top of the insert after insertion in the base plate. Additionally, the high surface-to-volume ratio of the membrane compartment allows rapid dialysis, where equilibrium can be reached in 4 hours with high levels of reproducibility and accuracy. In many cases, experiments can be completed in less than 100 minutes.

Insert Features:
• Disposable: require no presoaking, assembly, or specialized equipment
• Short incubation time: large dialysis surface area accelerates equilibrium
• 8K MWCO membrane: ideal molecular-weight cutoff for protein-drug binding studies
• 12K MWCO membrane also available for larger drug molecules
• Membrane composition: regenerated cellulose with low glycerol content as a humectant

Features of the RED Device Base Plates:
RED Device Inserts are designed to be used with either the reusable PTFE or disposable high-density polypropylene base plates. Each RED Device Base Plate holds up to 48 RED Device Inserts and has a standard 96-well plate footprint with 9mm x 9mm well spacing to provide compatibility with automated liquid handling systems. In addition, the disposable RED Device Base Plates are available pre-loaded, providing operation convenience for scientists conducting protein-binding applications. No pre-conditioning of the membrane inserts is needed. When using radioactive materials, this single-use plate is easily disposed of to avoid contamination and cleaning. RED Device Inserts and Base Plates are also available separately.

Base Plate Features:
• Microplate footprint: compatible with automated systems for 96-well plates
• Compartmentalized: eliminates potential for crosstalk or leakage
• PTFE construction: eliminates nonspecific binding and risk of contamination
• Accepts 1 to 48 inserts: run exactly the number of assays needed without waste

Applications:
• Determination of free vs. drug bound to plasma proteins
• Pharmacokinetics studies
• Formulation of drug dosage for in vivo studies
• Drug-drug interaction studies
• Selection criteria during drug lead optimization
• Drug partition between plasma and whole blood
• Solubility study
• Dissociation constant determination (Kd)
• Tissue-binding study using tissue homogenate

Determining the extent to which a molecule binds to plasma proteins is a critical phase of pharmaceutical development because it influences compound dosing, drug efficacy, clearance rate and potential for drug interactions. This determination is enabled by equilibrium dialysis, an accepted standard method for reliable estimation of the nonbound drug fraction in plasma. Although it is the preferred method, equilibrium dialysis is generally labor-intensive, time-consuming, cost-prohibitive and difficult to automate. The RED Device for rapid equilibrium dialysis was developed in close association with the pharmaceutical industry to specifically address these issues, accelerating lead optimization and reducing the attrition rate. In addition to plasma protein binding, the device is used for determining drug partition between red blood cell and plasma, protein binding of liver microsomes to improve the correlation between in vitro and in vivo intrinsic clearance, the competition between tissue protein binding against plasma proteins and dissociation constant determination (Kd).

The RED Device has been extensively validated for plasma-binding assays producing results consistent with those reported in the literature. For example, when used to measure warfarin binding to plasma (human and rat) proteins at two concentrations of 1 µM and 10 µM, the RED Device produced results with minimal intra-experimental variability. The Rapid Equilibrium Dialysis (RED) Device offers significant improvements in automation, time requirements, versatility and product reliability compared to other commercially available systems.

The 12 mL size is convenient for preparative applications
Slide-A-Lyzer Dialysis cassettes are available in four different sizes to accommodate sample volumes between 0.1 and 30 mL. These devices are easier to use than traditional dialysis tubing, providing both faster buffer exchange and more complete sample recovery. Slide-A-Lyzer Cassettes can be used for a wide range of applications including low molecular-weight contaminant removal, buffer exchange, desalting, equilibrium dialysis, and sample concentration. Liquid samples are easily added and removed by penetrating the self-sealing gasket with a hypodermic needle attached to a syringe. No knots, clips or caps are needed to seal the units and prevent leaking and sample-loss during the dialysis procedure.

Gamma-irradiated Dialysis Cassettes:
Gamma-irradiated Slide-A-Lyzer Dialysis Cassettes are ideal for researchers culturing cells and microorganisms; purifying viruses, DNA and RNA; or performing sample preparation for other applications requiring conditions that minimize the risk of sample contamination. The gamma-irradiated cassettes are treated with 20-36 kGy of gamma radiation, a dosage that has been determined to sterilize the units based on both trypticase soy broth medium for identifying total growth and fluid thioglycollate medium for identifying anaerobic growth. However, a confirmation of sterility is not provided for individual lots, as no further sterility testing is conducted post irradiation.

Slide-A-Lyzer Dialysis Cassettes are constructed from two sheets of low-binding, regenerated-cellulose dialysis membrane that are hermetically sealed on either side of a silicone-like gasket inside an inert plastic frame. The membrane and cassette materials are compatible with most common laboratory chemicals and buffers.
