Description
OverviewAn excellent peptide substrate for calcineurin (Protein Phosphatase 2B, PP2B; Cat. No. 539568). The sequence is derived from the PKA regulatory subunit type II (RII) and is phosphorylated on the Ser residue. Release of phosphate can be quantified colorimetrically using the malachite green method.

Recommended reaction conditions
Malachite Green Assay Note: This protocol is provided only as a general guide. Researchers should standardize this assay for their own specific needs and should consult published literature. Reagents • 4.2% Ammonium molybdate: prepare a 4.2% (w/v) solution of ammonium molybdate in 4 M HCl • Malachite Green: prepare a 0.045% (w/v) solution of malachite green • Malachite Green Solution: Mix 1 volume of 4.2% ammonium molybdate (prepared as above) with 3 volumes of 0.045% malachite green (as prepared above); stir for a minimum of 30 min; filter sterilize using a 0.22 µm filter. This solution is stable at 4°C for 6 months. • Malachite Green/Tween Solution: 0.01% Tween®-20 detergent (v/v) is added to an aliquot of Malachite Green Solution just prior to use • 2X assay buffer: 200 mM NaCl, 100 mM Tris, 12 mM MgCl2, 1 mM CaCl2, 1 mM DTT, 0.05% NP-40, pH 7.5. Assay buffer can be stored in aliquots at -70°C. • Calcineurin Substrate: Prepare a 750 µM (1.64 mg/ml) stock solution in H2O • Calmodulin, Bovine Brain (Cat. No. 208690 or 208694): prepare a 25 µM stock solution in H2O. Prepare a working solution of calmodulin by diluting the stock solution 1:50 in 2X assay buffer; a total of 25 µl is needed per reaction. • Cell lysate or purified PP2B (Calcineurin) (Cat. No. 539568) • Phosphatase inhibitors, as desired • 1/2 volume plate • KH2PO4: prepare a phosphate standard stock solution by dissolving in 0.05 N HCl to an appropriate concentration of phosphorous (nmol or pmol/ml). Prepare serial dilutions just prior to use for generation of a standard curve. Use 25 µl of each standard dilution plus 25 µl of 2X assay buffer; add 100 µl of Malachite Green/Tween Solution and measure absorbance (see below). • Plate reader capable of measuring absorbance at 620 nm Protocol • Prepare phosphate standard samples in the desired number of wells in a microtiter plate. It is recommended that the standards be performed in duplicate. • Prepare sample wells: • 25 µl of 2X assay buffer • 10 µl of Calcineurin Substrate • 5 µl of Calcineurin preparation (cell lysate or ~40 U of purified enzyme) Note: control samples may be included by the addition of appropriate phosphatase inhibitors. Adjust the H2O volume appropriately to maintain a 50 µl total reaction volume. • Incubate for the desired time (e.g. 30 min at 30°C) • Terminate the reactions by adding 100 µl of Malachite Green/Tween Solution to each well. Continue incubating for 15-30 min. • Read the absorbance at 620 nm. • Compare samples to the standard curve to determine phosphatase activity.
