Summary: A complete colorimetric assay kit for measuring cellular calcineurin (PP2B) phosphatase activity. It employs a convenient 96-well plate format with all reagents necessary for measuring calcineurin (PP2B) phosphatase activity in tissue/cellular extracts PLUS human recombinant calcineurin is included as a positive control. The RII phosphopeptide substrate, supplied with this kit is the most efficient and selective peptide known for calcineurin. The detection of free-phosphate released is based on the classic malachite green assay. http://www.creativebiomart.net/Cellular-calcineurin-activity-assay-Kit-462425.htm
