NKcellcytotoxicityassay
Outline:To measure NK cell killing, suitable target cells are labeled with 51Cr, washed and incubated together with the killer cells (and treatments). Large amounts of label is released into the supernatant upon disruption of membrane integrity by the killing process and can be measured in a gamma-counter.Supplies & Equipment:37°C waterbath (with lead container for 50 ml tube to shield gamma radiation, withi......閱讀全文
