PDE4B, phosphodiesterase 4B

≥ 3882 pmol/min/µg

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.

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 dPDE4B 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 pH 8, 110 mM NaCl, 2.2 mM KCl, 20% glycerol, 3 mM DTT

Aqueous buffer solution

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
