PDE4A isoform 1, PDE4A4B
Specific Activity:
≥ 11,610 pmol/min/µg
Unit Definition:
One unit is defined as the amount of enzyme that will convert 1 pmole of 3', 5'-cAMP to 5'-AMP per minute at 37°C.
Assay Conditions:
Assayed using BPS's PDE4A Assay Kit, Cat. # 60340. Assay conditions: 10 mM Tris-HCl, pH 7.4, 10 mM MgCl2, 0.1 mg/ml BSA, 0.05% Tween-20, 200 µM cAMP, 2.5 kU 5'-nucleotidase, and serial dilutions of PDE4A4B at 37°C for 20 min. Quantified by 5'- nucleotidase cleaving the 5' -AMP product and releasing the phosphate group which is detected by Malachite Green Reagent.
40 mM Tris-HCl, pH 8.0, 110 mM NaCl, 2.2 mM KCl, 4 mM glutathione, 3 mM DTT and 20% glycerol
Aqueous buffer solution
