Commercially available ADP is contaminated with trace amounts of ATP. In bioluminescence assays this trace ATP contamination results in high backgrounds and reduces assay sensitivity. Cell Technology's ADP is purified to remove these trace ATP contaminants and as a result produces ADP that is greater than 99.9% pure.
This ADP is designed for use in bioluminescence applications where minimal background ATP contamination is required. ADP can be used as a substrate in enzymatic reactions to generate ATP. Subsequently ATP can be detected via the bioluminescence reaction of luciferase/luciferin.
