realizes has_specified_input inheres in reagent role cytometry assay mixed lymphocyte reaction assay A cytometry assay where lymphocytes from two individuals are co-cultured with the lymphocytes from one of the allogeneic individuals (Responders) being labeled (with 3H Thymidine or BrdU) and the proliferation of the labeled cells is measured, which is thought to reflect recognition of histocompatibility antigens on the unlabeled cells (stimulators). ImmPort MLR PMID:14969764 T cells were separated from PBL of laboratory volunteers and used as responder cells (R). Mitomycin C-treated allogeneic mAPC enriched populations were used as stimulators (S), incubated for 5 days, pulsed with 3H-thymidine (3H-TdR) for 16 hours, harvested, and radioactivity counted using a beta scintillation counter to measure proliferation of the 3H-thymidine labeled cells. mixed lymphocyte reaction assay molecular label metadata complete
