EasySep Biotin Pos Slctn Kit II-Sam

Rapid magnetic isolation of target cell populations from heterogeneous single-cell suspensions is the core capability of this positive selection system from STEMCELL Technologies. The biotin-based chemistry lets researchers use any biotinylated antibody directed against a surface marker of interest, after which dextran-coated superparamagnetic particles bind biotin-labeled cells and pull them to the magnet wall during short incubation steps. Because no columns or density gradients are required, the protocol typically finishes in roughly 15 minutes and integrates with manual or fully automated EasySep magnet workflows.

The kit is commonly adopted in immunology, stem cell biology, and translational research labs for isolating defined subsets such as lymphocyte populations, progenitor cells, or rare circulating cells from peripheral blood mononuclear cells, splenocytes, or enzymatically dissociated tissue. Each box contains the magnetic particle suspension and required buffers shipped in sealed vials and stored refrigerated until first use. Downstream applications include flow cytometry phenotyping, in vitro culture expansion, and nucleic acid extraction from purified populations.

The flexible biotin-antibody approach supports both human and mouse primary samples and lets laboratories tailor selection to non-standard targets not covered by pre-conjugated reagent kits, while the sample-scale format supports pilot optimization before scaling to larger tissue preparations.
