Product description and procedure summary:If your target cells are the labeled cells (the positive fraction), use the Streptavidin Nanobeads Protocol \u2013 Positive Selection. If your target cells are the unlabeled cells (negative fraction), use the Streptavidin Nanobeads Protocol - Negative Selection.\n\nTarget cells are isolated by incubating your sample with a Biotin-conjugated antibody or antibody cocktail, followed by incubation with magnetic Streptavidin Nanobeads (Cat. No. 480015\/480016). The magnetically labeled fraction is retained by the use of a magnetic separator. The untouched cells are collected. These are the cells of interest; do not discard the liquid. Some of the downstream applications include functional assays, gene expression, phenotypic characterization, etc.Note:\u00a0This procedure is optimized for the isolation of 107 to 2 x 108 cells per tube. If working with fewer than 107 cells, keep volumes as indicated for 107 cells. For best results, optimize the conditions to your specific cell number and tissue. Prepare fresh MojoSort\u2122 Buffer solution by diluting the 5X concentrate with sterile distilled water.\n\nScale up volumes if using 14 mL tubes and Magnet, and place the tube in the magnet for 10 minutes.
