WebMar 2, 2024 · Real-time cytolysis potency assays and derivation of KT 50 values. In order to assess cytolysis of target cells as a function of time and effector cell number using the RTCA potency assay, nuclear red PC3 cells were treated with NK-92 at E:T ratios ranging from 10:1 to 0.625:1 using quadruplicate wells. Cytotoxicity can also be measured by the sulforhodamine B (SRB) assay, WST assay and clonogenic assay. Suitable assays can be combined and performed sequentially on the same cells in order to reduce assay-specific false positive or false negative results.
