ADP-Glo Kinase Assay + MAPKAPK2 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 MAPKAPK3 Kinase Enzyme System contains:

• MAPKAPK3 Kinase, 10μg (Human, recombinant full-length). MW: ~69kDa.
• HSP27tide(RRLNRQLSVA-amide) Substrate; derived from the mouse HSP27 (amino acids 8085).
• Reaction Buffer, DTT.

Recombinant full-length human MAPKAPK3 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. MAPKAPK3 is closely related to MAPKAPK2 sharing 72% nucleotide and 75% amino acid identity. MAPKAPK3 is activated by growth inducers and stress stimulation of cells. In vitro studies demonstrated that ERK, p38 MAP kinase and Jun N-terminal kinase were all able to phosphorylate and activate this kinase, which suggested the role of MAPKAPK3 as an integrative element of signaling in both mitogen and stress responses.

The MAPKAPK3 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.
