CrReleaseCytotoxicityassay

DescriptionCytotoxic activities of mNK cells are examined in 51Cr release assay from target cells ProcedureEffector cells (mNK cells) are seeded into round-bottom 96-well plates (Costar) in 100-?l aliquots/well and at appropriate concentrations. Tumor cells, K562 are used as targets. Tumor targets (1 x 106 cells/mL) are incubated with 100 ?Ci sodium chromate (The Radiochemical Centre, Amersham, GB)for 60 min at ......阅读全文
