Product Details
| Alternative Name: | Protein phosphatase 2B, PP2B |
| |
| MW: | 60 kDa (calcineurin Aα) + 15 kDa (calcineurin B) |
| |
| Source: | Produced in E. coli. Human calcineurin Aα (MW 60kDa) and calcineurin B (MW 15kDa) heterodimer. Both subunits are coexpressed in a construct with yeast myristoyl-CoA:protein N-myristoyltransferase. The resulting highly active calcineurin (protein phosphatase 2B) is N-myristoylated on the CaNB subunit, similar to the native protein. |
| |
| UniProt ID: | Q08209 (subunit Aα), P63098 (subunit Bα) |
| |
| Concentration: | 100 U/µl |
| |
| Formulation: | Liquid. In 1X KI-128 Assay Buffer with increased DTT concentration (50mM TRIS, pH 7.5, containing 100mM sodium chloride, 6mM MgCl2, 5mM DTT, 0.025% NP-40 and 0.5mM CaCl2). |
| |
| Purity: | ≥90% (SDS-PAGE) |
| |
| Specific Activity: | One U= 1pmol/min using 0.15mM RII phosphopeptide substrate (Prod. No. BML-P160) in the presence of calcium/calmodulin at 30°C. In the absence of calmodulin, the activity is <1%. |
| |
| Application Notes: | Useful for the study of enzyme kinetics, regulation, to dephosphorylate target substrates, and for screening inhibitors. Enzyme activity may be determined using the BIOMOL GREEN Calcineurin Assay Kit (Prod. No. BML-AK804). |
| |
| Shipping: | Dry Ice |
| |
| Long Term Storage: | -80°C |
| |
| Handling: | Avoid freeze/thaw cycles. After opening, prepare aliquots and store at -80°C. |
| |
| Regulatory Status: | RUO - Research Use Only |
| |
SDS-PAGE Analysis: Lane 1: MW Marker; Lane 2: 1.0 μg of purified human recombinant calcineurin protein (SE-163).
