Phospho-Chk1 (Ser280) Antibody (MA5-55308) in WB

Western blot analysis of lysates from 293T cells, using Phospho-Chk1 (Ser280) Recombinant Monoclonal Antibody (Product # MA5-55308) at 1:500 dilution. 293T cells were treated by Calyculin A (100 nM) at 37&(8)451; for 30 minutes followed by a HRP-conjugated Goat anti-Rabbit IgG (H+L) secondary antibody at 1:10,000 dilution. Lysates/proteins: 25 μg per lane. Blocking buffer: 3% nonfat dry milk in TBST. Detect... View More {{ $ctrl.currentElement.advancedVerification.fullName }} validation info. View more

Target Information

CHEK1 (CHK1) is a serine/threonine protein kinase involved in preventing replication when DNA integrity is compromised. CHK1 is a key mediator in the DNA damage-induced checkpoint network. CHK1 is an evolutionarily conserved protein kinase that functions to ensure genomic integrity upon genotoxic stress. When the G2 or S checkpoint is abrogated by the inhibition of CHK1, p53-deficient cancer cells undergo mitotic catastrophe and eventually apoptosis, whereas normal cells are still arrested in the G1 phase. Thus, CHK1 inhibitors can preferentially potentiate the efficacy of DNA damaging agents in cancer cells, and Chk1 is an attractive therapeutic target for cancer treatment, especially since approximately 50% of all human cancers are p53-deficient.
