PP2B, Human, Recombinant, E. coli

Recombinant, human calcineurin Aα (catalytic subunit) and calcineurin B (regulatory subunit) co-expressed with yeast myristoyl-CoA:protein N-myristoyltransferase. A Ca²⁺/CaM-dependent protein phosphatase. The resulting highly active calcineurin is N-myristoylated on the CaN B-subunit, as is the native protein. M.W. 60,000 (A subunit) and 15,000 (B subunit).

In 100 mM NaCl, 50 mM Tris, 6 mM MgCl₂, 5 mM DTT, 0.5 mM CaCl₂, 0.025% NP-40.

Following initial thaw, aliquot and freeze (-70°C). Please refer to vial label for lot-specific reconstitution volume.
