Synthetic peptide corresponding to the C-terminal region of human Puma. Cellular Localization: Mitochondrion. Species sequence homology: human.
PUMA is one of the pro-apoptotic Bcl-2 family members including Bax and Noxa, which are also transcriptional targets of p53. The PUMA gene encodes two BH3 domain-containing proteins termed PUMA-a and PUMA-b. PUMA proteins bind Bcl-2, localize to the mitochondria, and induce cytochrome c release and apoptosis in response to p53. PUMA may be a direct mediator of p53-induced apoptosis. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:250 Optimal dilutions to be determined by the researcher. Positive Control: Mouse brain lysate Storage and Stability: May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. Note: Applications are based on unconjugated antibody.
