Sensitive Adenylate Kinase Assay

The ToxiLight BioAssay Kit determines cytotoxicity by measuring the activity of the enzyme Adenylate Kinase that is released from cells when they die. As the number of lysed cells increases, Adenylate kinase accumulates in the supernatant, which results in a higher signal from the ToxiLight™ reagent.

Unlike many other cytotoxicity assays, there is no need for cell lysis. This makes the assay very fast and simple and allows you to take repeated samples from the same well over time without disrupting the cells. In addition, the cells may be used for other analyses, such as RNA or protein.

The assay signal is very stable, which enables batch processing in high-throughput screening applications.
