Rat PDE2A (GenBank Accession No. NM_00143847), full length, with N-terminal His-GST-tag, MW=133 kDa, expressed in a Baculovirus infected Sf9 cell expression system

Q01062

PDE2A, phosphodiesterase 2A

≥ 2500 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 PDE2A 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, 20% glycerol, and 3 mM DTT

Aqueous buffer solution

>6 months at -80°C.

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

Application Reference(s):
A yeast-based chemical screen identifies a PDE inhibitor that elevates steroidogenesis in mouse Leydig cells via PDE8 and PDE4 inhibition (2013)

Avoid freeze/thaw cycles. Storing diluted enzyme is not recommended, if necessary, use carrier protein (BSA 0.1 - 0.5%).
