Human PDE4A1A (GenBank Accession No. U97584), full length protein with N-terminal GST tag (MW = 100kD), expressed in a Baculovirus infected Sf9 cell expression system.
Specific Activity:Lot Specific. Sample Lot Value: 4,176 pmol/min/ug.
Unit Definition:One unit is defined as the amount of enzyme that will convert 1 pmole of 3′, 5′-cAMP to 5′-AMP per min at 37°C. Assay Conditions: 10mM Tris-HCl, pH 7.4, 10mM MgCl2, 1mM MnCl2, 200uM cAMP, and 0.2ng/ul PDE4A1A 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.
Applications:Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Recommended Dilution:Optimal dilutions to be determined by the researcher.
Storage and Stability:Aliquot to avoid repeated freezing and thawing and store at -70°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Aliquots are stable for at least 6 months.
