Human PDE5A1 (GenBank Accession No. NM_001083), full length, with N-terminal GST-tag, MW=126 kDa, expressed in a Baculovirus infected Sf9 cell expression system.
PDE5A, phosphodiesterase 5A
Specific Activity:
≥ 3100 pmol/min/µg
Unit Definition:
One unit is defined as the amount of enzyme that will convert 1 pmole of 3', 5'-cGMP to 5'-GMP per minute at 37°C.
Assay Conditions:
Assayed using BPS's PDE5A kit, Cat. # 60350. Assay conditions: 10 mM Tris-HCl, pH 7.4, 10 mM MgCl2, 0.1 mg/ml BSA, 0.05% Tween-20, 200 µM cGMP, 2.5 kU 5'-nucleotidase, and serial dilutions of PDE5A1 at 37°C for 20 min. Quantified by 5'- nucleotidase cleaving the 5' -GMP product and releasing the phosphate group which is detected by Malachite Green Reagent.
40mM Tris pH 8.0, 110mM NaCl, 2.2mM KCl, 0.04% Tween-20, 20% glycerol, 3mM DTT
Aqueous buffer solution
