Background
CHK2 (checkpoint kinase 2, also known as CHEK2) is an evolutionarily conserved serine/threonine protein kinase that operates as a cell cycle checkpoint in response to DNA damage. Thus, it is rapidly phosphorylated and activated upon DNA damage. It is known to phosphorylate and inactivate phosphatase Cdc25C, thereby preventing entry into mitosis. CHK2 also stabilizes tumor suppressor TP53 and is a key player in the ATM DNA damage response and repair pathway. CHK2 mutations are observed in Li-Fraumeni syndrome, an inherited predisposition to cancer. Mutations in CHK2 are also linked to various spontaneous types of cancer.
Storage/Stability
This assay kit will perform optimally for up to 6 months from date of receipt when the materials are stored as directed.
Applications
Study enzyme kinetics and screen small molecular inhibitors for drug discovery and high throughput (HTS) applications.
The final concentration of DMSO in the assay should not exceed 1%.
Warnings
Avoid freeze/thaw cycles
Disclaimers and Limitations
BPS Bioscience assay kits are validated using the listed components according to our specific protocol. Any deviations to kit components or protocols, such as using different proteins, cell/tissue lysates, or buffers (including using the same component from other commercial sources) will void any warranties on the performance of the assay kit and is not recommended.
End-users should immediately report any issues to [email protected] upon receipt of the kit, such as missing components, damaged vials, no dry ice, etc.
