Cytotoxicity Inhibition Assay: Cryopreservation and Standardization: Brief Communication

Abstract

The cytotoxicity inhibition assay is an extremely useful tool for examination of the specificity of cell-mediated cytotoxicity. With this demonstration of cryopreservation of the attacker, target, and inhibitor cells, a powerful new tool is available for the standardization of this assay to better examine the specificity of cytotoxicity assays. Not only can cryopreservation be used to standardize the assay within a single laboratory, but also reagents may now be exchanged between laboratories to better understand the differences in cell-mediated cytotoxicity as observed by different investigators.
