Dynabeads™ FlowComp™ Mouse CD4 Kit Invitrogen™
This gentle and easy-to-use kit allows you to isolate flow-compatible mouse CD4+ T cells. Immediately after positive isolation, the beads are released and removed from your cell sample. In this way, you avoid exposing your cells to potentially cytotoxic or immunogenic foreign substances like iron oxides or dextrans, a potential problem when working with biodegradable particles. In addition, your cells will not be exposed to the stress of being passed through a column.
You can expect a purity level of >85% and viability of >85% of mouse CD4+ cells.
Advantages:
• No risk of your results being affected by the isolation method
• Gentle tube-based method - no columns needed
• High purity, recovery and viability
• Bead-free cells - compatible with flow cytometry analysis
• Viable, bead-free CD4+ T-cells for direct use in any cell-based assay.
The isolated cells have the presumed profile of memory and naive CD4+ T cells, and show a high proliferation capacity. You will save time and money, and get increased confidence in your results.

Fluoro-Max Dyed Green Aqueous Fluorescent Particles Thermo Scientific™
Improve sensitivity and detectability for analytical methods with Thermo Scientific™ Fluoro-Max Green Aqueous Fluorescent Particles, microsphere suspensions that are internally dyed and feature bright, high-contrast colors.
SCF Human ProcartaPlex™ Simplex Kit Invitrogen™
The Human SCF Simplex ProcartaPlex Kit measures SCF protein and is designed to be combinable with other Simplex kits so that you can create your own multiplex panel that utilizes Luminex xMAP technology for protein detection/quantitation. When combining multiple Simplex kits (i.e., when you are not using a pre-configured Multiplex Panel), only one buffer kit (sold separately) is needed for each assay plate regardless of plex size.
About ProcartaPlex Assays for the Luminex Platform
ProcartaPlex immunoassays are based on the principles of a sandwich ELISA, using two highly specific antibodies binding to different epitopes of one protein to quantitate all protein targets simultaneously using a Luminex instrument. ProcartaPlex multiplex assays require as little as 25 µL of plasma or serum, or 50 µL of cell culture supernatant, and just four hours to obtain analyzed results.
• More results per sample—measure multiple protein targets simultaneously in a single 25–50 µL sample
•Well-established Luminex technology—highly referenced multiplexing platform for protein detection and quantitation
ProcartaPlex assays utilize Luminex xMAP (multianalyte profiling) technology for the simultaneous detection and quantitation of up to 65 protein targets in a single 25–50 µL sample from plasma, serum, cell culture supernatants, and other bodily fluids.
The Luminex beads in the ProcartaPlex assay are internally dyed with precise proportions of red and infrared fluorophores to create spectrally unique signatures that can be identified by the Luminex xMAP detection systems (e.g. Luminex 200, FLEXMAP 3D, and MAGPIX). Similar to a sandwich ELISA, the ProcartaPlex assay uses matched antibody pairs to identify the protein of interest. In a multiplexed assay, each spectrally unique bead is labeled with antibodies specific for a single target protein, and bound proteins are identified with biotinylated antibodies and streptavidin–R-phycoerythrin (RPE). The conjugation of protein-specific antibodies to a distinct bead allows for analysis of multiple targets in a single well.
The most significant difference between a ProcartaPlex assay and ELISA is that the capture antibody in the ProcartaPlex assay is conjugated to a bead and not adsorbed to the microplate well, so the ProcartaPlex assay reagents are free-floating in the solution. For detection, the Luminex 200 instrument, for example, contains two lasers, one to distinguish the spectral signature of each bead and the second to quantify the amount of RPE fluorescence, which is proportional to the amount of protein present in the sample. ProcartaPlex multiplex assays can profile more target proteins using significantly less sample in the same time that it takes to perform a traditional sandwich ELISA.
ProcartaPlex multiplex panels are available in multiple formats across six species (human, mouse, rat, nonhuman primate, porcine, and canine). Visit thermofisher.com/procartaplex for more information, including a comprehensive list of individual protein targets.

OneComp eBeads™ Compensation Beads Invitrogen™
OneComp eBeads react with antibodies of mouse, rat and hamster origin, and are immunoglobulin light chain-independent. The beads are spherical particles that can be stained with individual fluorochrome-conjugated antibodies for use as single-color compensation controls.
Each drop of beads contains two populations: a positive population that will capture any mouse, rat or hamster antibody and a negative population that will not react with antibody. When a fluorochrome-conjugated antibody is added to the beads, both positive and negative populations result. This bimodal distribution can be used for single-color compensation controls in multicolor flow cytometry experiments.
OneComp eBeads cross-react to some antibodies of rabbit origin, but have not been extensively tested for this reactivity. OneComp eBeads are designed for use in compensation with all fluorochromes excited by blue (488 nm), green (532 nm), yellow-green (561 nm), and red (633-635 nm) lasers. This product is compatible with eFluor™ 450 but is not optimized for compensation of other fluorochromes excited by a violet (405 nm) laser.

Dynabeads™ M-450 Tosylactivated Invitrogen™
Dynabeads® M-450 Tosylactivated are 4.5 µm superparamagnetic beads containing surface tosyl groups. The beads covalently bind primary amino and sulfhydryl groups in antibodies to position them in the optimal orientation for cell-surface protein binding. Low background and covalent binding of the antibodies make these beads an excellent choice for cell separation applications when a downstream release from the beads is not required.
• Quickly deplete cells or positively isolate target cells for downstream molecular analysis
• Excellent for cell isolation procedures using your own unique antibody
• Several antibodies can be coupled on the same beads for non-cell-based applications, such as cell activation
Coupling procedure
Covalent coupling is performed overnight by incubating the antibody of choice with the Dynabeads® M-450 Tosylactivated beads. Optimal coupling occurs at high pH (8.5–9.5) and at 37°C. For pH-labile antibodies, coupling can be performed in an alternative buffer at pH 7.4.
Not recommended for immunoprecipitation (IP)
These 4.5 µm Tosylactivated beads are not recommended for IP as they have a lower surface capacity per unit mass when compared to 1 µm and 2.8 µm Tosylactivated and Epoxy Dynabeads®.

ReadyProbes™ Cell Viability Imaging Kit, Blue/Red Invitrogen™
ReadyProbes® Cell Viability Imaging Kit (Blue/Red) is a ready-to-use kit that can quickly and easily determine the viability of cells. Just add 2 drops each of room temperature, stable NucBlue® Live reagent (Hoechst 33342) and propidium iodide to 1 mL of cell growth media, then determine viability by counting total vs dead cells. NucBlue® Live reagent stains the nuclei of all the cells and can be detected using a standard DAPI filter. Propidium iodide stains only the nuclei of cells with compromised plasma membrane integrity and is detected with a standard TRITC/RFP (orange) filter set. This kit is appropriate for fluorescence microscopy, fluorescence micro plate readers, and flow cytometry.
NucBlue® Live reagent: stains the nuclei of all cells; detected with a standard DAPI filter (excitation/emission maxima: 360/460 nm)
Propidium iodide: stains the nuclei of dead cells with compromised plasma membrane; detected with standard TRITC/RFP (orange) filter set (excitation/emission maxima: 535/617 nm)
See other ReadyProbes® reagents for cell staining
Learn more about other assays for cell viability
Suggestions for use
• NucBlue® Live reagent and propidium iodide can be added directly to cells in full growth media or a compatible buffer solution.
• In most cases, 2 drops/mL and an incubation time of 5 to 30 minutes will give bright nuclear staining; however, optimization may be needed for some cell types, conditions, and applications. In such cases, simply add more or fewer drops until the optimal staining intensity is obtained.
