Find out why the Cell Counting Kit-8 (CCK-8) from Dojindo is the most effective cell proliferation and cytotoxicity assay available today. Because the Dojindo CCK-8 kit is not cytotoxic, the cells being tested can remain in culture and be used downstream for RNA or protein isolation, something that is not possible with a standard MTT Assay. Based on the measurement of NAD(P)H levels, the CCK-8 cell counting kit is a sensitive, colorimetric assay with high reproducibility. The CCK-8 kit has been optimized for a wide variety of research applications including drug screening and drug discovery. Distributed by Tubemogul.
