  • Safe and non-radioactive assay
  • Convenient 1-step detection
  • Excellent sensitivity
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.

Cellular CaN Assay Using Mouse Brain Phosphatase activity from a freshly prepared mouse brain extract. Prior to gel filtration the extract was diluted 1:1 in lysis buffer containing protease inhibitors. After gel filtration and prior to the phosphatase assay, the extract was diluted 1/25 in lysis buffer. Well contents were as in manual. The reaction was incubated for 30 min at 30°C.

CaN Positive Control. Purified calcineurin (BML-SE163-9090) positive control. The CaN was incubated 1 hr at 30°C under various buffer conditions. The results demonstrate that CaN activity is inhibited by the EGTA buffer, but not inhibited by 100nM or 500nM concentrations of okadaic acid

Product Specification

Applications:Colorimetric detection
Use/Stability:Store all components except the microtiter plate at -70°C for the highest stability. The calcineurin enzyme component SE163-9090 must be handled particularly carefully in order to retain maximal enzymatic activity. Thaw it quickly in a RT water bath or by rubbing between fingers, then immediately store on an ice bath. The remaining unused enzyme should be quickly refrozen by placing at -70°C. To minimize the number of freeze/thaw cycles, aliquot the calcineurin into separate tubes and store at -70°C.
Shipping:Shipped on Dry Ice
Long Term Storage:-80°C
Kit/Set Contains:

Calcineurin enzyme, Calmodulin (human, recombinant), Substrate (RII phosphopeptide), 2x assay buffer, EGTA Buffer, Lysis Buffer, Protease inhibitor cocktail, Biomol Green™ Reagent, Phosphate standard, Okadaic acid, Desalting column and resin, ½-Volume microplate
