Features of Slide-A-Lyzer MINI Dialysis Device, 3.5K MWCO, 0.1 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 3.5K 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 to 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.

NAb™ Protein G Spin Columns, 5 mL Thermo Scientific™

The Thermo Scientific NAb Protein G Spin Columns are convenient for rapid, small-scale affinity purification of antibodies from a variety of sample types. Each column containing 5 mL of the immobilized protein resin enables quick purification of 5-65 mg of IgG from 2-10 mL of serum or other sample. The actual amount of IgG purified varies depending upon the sample type and the specific spin column used.

Pierce Protein G Agarose is a premium-quality affinity resin for antibody purification. It consists of recombinant Protein G that has been covalently immobilized onto high-quality crosslinked 6% beaded agarose (CL-6B). This particular variety of the affinity resin provides the most versatile combination of chromatographic features for high yield and high-purity purification of whole IgG from mammalian serum samples. The agarose beads have physical and chemical properties suitable for many affinity purification systems.

Features of Pierce Protein G Agarose:

Protein G – immobilized Protein G is ideal for polyclonal IgG purification from mouse, human, cow, goat and sheep serum, including human IgG3 and mouse IgG1 isotypes
Agarose resin – support is crosslinked 6% beaded agarose (CL-6B), the most popular resin for protein affinity purification methods
Inert and stable – superior manufacturing method immobilizes Protein G by charge-free, leach-resistant covalent bonds, resulting in low nonspecific binding and enabling multiple uses without decline in yield
Standard capacity – Pierce Protein G Agarose has a normal load of immobilized Protein G, providing a binding capacity of 11 to 15 mg human IgG/mL resin

Protein G is a bacterial cell wall protein original from group G Streptococcus and now produced as a recombinant in E. coli. Like Protein A, Protein G binds to most mammalian immunoglobulins primarily through their Fc regions. Native Protein G contains two immunoglobulin binding sites, as well as albumin and cell surface binding sites. In the recombinant form of Protein G, these albumin and cell surface binding sites have been eliminated to reduce nonspecific binding when purifying immunoglobulins. Recombinant Protein G has a mass of approximately 21.6kDa, but its apparent size by SDS-PAGE is 31 to 34kDa. IgG-binding function is optimal at pH 5 but also occurs efficiently in near-neutral conditions (pH 7.0 to 7.2).

Compared to Protein A, Protein G binds a broader spectrum of IgG subclasses from human, mouse and rat serum. In particular, besides binding other isotypes just as well as Protein A, Protein G exhibits stronger binding to human IgG3, mouse IgG1 and all three isotypes of Rat IgG. Thus, Protein G is generally recommended for applications involving these species and isotypes of antibody. With regard to other species, Protein G provides higher-capacity binding for IgG from cow, goat and sheep, but it binds more weakly than Protein A to pig, guinea pig, dog and cat IgG.

Pierce Protein G Agarose is prepared using Thermo Scientific AminoLink Coupling Chemistry, which provides several advantages compared to traditional methods of ligand immobilization. AminoLink Immobilization results in conjugation between sugar monomers of the agarose beads and native lysine residues on the Protein A via simple amide bonds. Unlike typical cyanogen bromide (CNBr) immobilization, the AminoLink Method does not introduce any novel chemical groups that could cause undesired nonspecific binding and produces a stable, essentially irreversible bond. The result is a high-binding-capacity resin that retains functional immobilized Protein G through multiple rounds of antibody purification.

Pierce Protein G Agarose is effective for affinity purification of IgG from serum and other fluids of many mammalian species. Protein G is especially well suited for use with mouse antibodies (including IgG1) in addition to most IgG isotypes from human, goat and sheep samples.

Properties of crosslinked 6% beaded agarose (CL-6B):
• Support pH Stability: 2 to 14 (short term); 3 to 13 (long term)
• Average Particle Size: 45 to 165 microns
• Exclusion Limit: 10,000 to 4,000,000 daltons
• Maximum Volumetric Flow Rate: approx. 1 mL/minute (for 1 cm diameter column)
• Maximum Linear Velocity: 30 cm per hour
• Maximum Pressure: less than 25psi (1.5 bar), defined as the maximum pressure drop across a column that the resin can withstand (Note: The indicated gauge pressure of a liquid chromatography apparatus may be measuring the total system pressure rather than the pressure drop across the column.)
