PUMA, alpha (p53 Upregulated Modulator of Apoptosis)
Description:
PUMA, (p53 upregulated modulator of apoptosis), is activated by p53 in cells undergoing p53-induced apoptosis (1-2). Localized in the mitochondria PUMA induces cytochrome c release and activates the rapid induction of programmed cell death. PUMA interacts with Bcl2 (3), Bcl-XL, Bcl2-like-1 protein and promotes mitochondrial translocation and multimerization of BAX. PUMA also plays a role in mediating p53-induced cell death through the cytochrome c/APAF1-dependent pathway (2). Two isoform of PUMA are known; PUMA-alpha and PUMA-beta.

Applications:
Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 1:30
Western Blot: 1:1000-5000
Immunoprecipitation: 1:50
Immunohistochemistry: 1:100-250
Immunocytochemistry: 1:250-500
Optimal dilutions to be determined by the researcher.
