The Kinase Enzyme Systems include a recombinant kinase enzyme, a substrate appropriate for the enzyme, a reaction buffer and supplemental reagents as needed. The ERK1 Kinase Enzyme System contains:
ERK1 Kinase, 10μg (Human, recombinant full-length). MW: ~44kDa.
Native Swine Myelin Basic Protein (MBP) Substrate.
Reaction Buffer, DTT.
Recombinant full-length, tag-free human ERK1 was expressed by baculovirus in Sf9 insect cells and activated by active MEK1 in vitro. ERK1 is a protein serine/threonine kinase that is a member of the extracellular signal-regulated kinases (ERKs), which are activated in response to numerous growth factors and cytokines. Activation of ERK1 requires both tyrosine and threonine phosphorylation that is mediated by MEK. ERK1 is ubiquitously distributed in tissues with the highest expression in heart, brain and spinal cord. Activated ERK1 translocates into the nucleus, where it phosphorylates various transcription factors (e.g., Elk-1, c-Myc, c-Jun, c-Fos and C/EBP beta).

The ERK1 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.
