Rabbit polyclonal to p53 ( phospho S15 )The p53 tumor suppressor protein plays a major role in cellular response to DNA damage and other genomic aberrations. The activation of p53 can lead to either cell cycle arrest and DNA repair or apoptosis. p53 is phosphorylated at multiple sites in vivo and by several different protein kinases in vitro. p53 can apparently be phosphorylated by ATM, ATR, and DNA-PK at Ser15; the phosphorylation impairs the ability of MDM2 to bind p53, promoting both the accumulation and functional activation of p53 in response to DNA damage.

Tested Applications
IHCIPWB
For IHC: Use at a concentration of 20 µg/ml. For IP: Use at a concentration of 5-10 µg/ml. For WB: Use at a dilution of 0.5-4 µg/ml. Optimal dilutions/concentrations should be determined by the researcher.:
The phospho-p53 (Ser15) antibody detects ~53 kDa phosphorylated p53 at Ser15. It does not react with non-phosphorylated p53 or p53 phosphorylated at other sites.
