CK1ε 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 CK2α1 Kinase Enzyme System contains:

• CK2α1 Kinase, 10μg (Human, recombinant full-length). MW: ~70kDa.
• Native Casein Protein Substrate purified from bovine milk.
• Reaction Buffer, DTT.

Recombinant full-length human CK2α1 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. CK2α1 is a serine-threonine protein kinase whose targets include many critical regulators of cellular growth. It is highly expressed in a lympho-proliferative disease of cattle and in many human cancers. Overexpression of the CK2 catalytic subunit in lymphocytes of transgenic mice leads to T cell lymphoma. The highest CK2α1 activity is found in mouse testicles and brain, followed by spleen, liver, lung, kidney and heart.

The CK2α1 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.
