This 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.Product description and procedure summary: The kit is designed for the isolation of human memory CD4 T cells from PBMC. Target cells are depleted by incubating your sample with the biotin antibody cocktail followed by incubation with magnetic Streptavidin Nanobeads. 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.
