Caspases have been shown to play a crucial role in apoptosis induced by various deleterious and physiologic stimuli. Inhibition of caspases can delay apoptosis, implicating a potential role in drug screening efforts. Caspase-2 is involved in the activation cascade of caspases responsible for apoptosis execution. BioVision’s CASP2 ELISA kit is a sandwich ELISA assay for the quantitative measurement of CASP2 in Rat serum, plasma and cell culture supernatants. The density of color is proportional to the amount of CASP2 captured from the samples.
