PKA Kinase Enzyme System

The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The PKA Kinase Enzyme System contains:

• PKA Kinase, 2,500 units (Bovine, recombinant full-length). MW: ~40kDa.
• Kemptide (LRRASLG) Substrate.
• Reaction Buffer, DTT.

Recombinant bovine cAMP-Dependent Protein Kinase (PKA), Catalytic Subunit, is expressed and purified from E. coli. Intracellular targets include ion channels, transcriptional activator proteins and regulatory enzymes of glycogen metabolism. PKA does not require cAMP for activity, and the gene sequence can be found at accession number NM_174584.

The PKA Kinase Enzyme System can be purchased with or without the ADP-Glo™ Kinase Assay reagents. Used together, the ADP-Glo™ Kinase Assay + Kinase Enzyme Systems provide a convenient method for profiling the effect of lead compounds on kinase activity. Assay advantages include broad dynamic range, ease of use and high sensitivity. Kinase Enzyme Systems are manufactured by SignalChem. Bulk quantities available upon request.

Use with ADP-Glo™ Kinase Assay

The ADP-Glo™ Kinase Assay is a luminescent kinase assay that measures ADP formed from a kinase reaction; ADP is converted into ATP, which is a substrate in a reaction catalyzed by Ultra-Glo™ Luciferase that produces light. The luminescent signal positively correlates with ADP amount and kinase activity. The assay is well suited for measuring the effects of chemical compounds on the activity of a broad range of purified kinases, making it ideal for both primary screening as well as kinase selectivity profiling. The ADP-Glo™ Kinase Assay can be used to monitor the activity of virtually any ADP-generating enzyme (e.g., kinase or ATPase) using up to 1mM ATP.
