Merck, SRP0266-5UG, PDE4C1 Active human

General description
Human PDE4C1 (GenBank Accession No. NM_000923), full length, with N-terminal GST tag, MW = 106 kDa, expressed in a Baculovirus infected Sf9 cell expression system.
Application
Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.
Physical form
Formulated in 25 mM Tris-HCl, pH 8.0, 100 mM NaCl, 0.05% Tween-20, 50% glycerol and 3 mM DTT.
Preparation Note
Thaw on ice. Upon first thaw, briefly spin tube containing enzyme to recover full content of the tube. Aliquot enzyme into single use aliquots. Store remaining undiluted enzyme in aliquots at -70°C. Note: Enzyme is very sensitive to freeze/thaw cycles.
Other Notes
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
