Enrichment of CD3 Cells by Removing Other Cell Populations (Negative Depletion)
The depletion of other cell types from leukopaks creates a highly enriched T cell population that has no capture reagents on their surface. This is accomplished through the use of a single targeting monoclonal antibody. Cells from leukopaks were washed by centrifugation and routinely resuspended at 1.0 x 108 cells/ml. Aliquots of cells were incubated with a set concentration of the “depleting” biotinylated monoclonal antibody and streptavidin ferrofluid. Cells were adjusted to a final concentration of 2.0 x 107 cells/ml and 4.0 ml of cell suspension was separated in the smaller FerroSelect QP5 Quadrupole and 12.5ml of cells separated in the larger QP15 magnet. The supernatants containing cells not captured by the magnetic field, i.e the cells of interest, were gently drained from the tube, counted and subjected to FACS analysis. Each experiment was undertaken three time with different starting products
