Independent Antibody Validation (Figure 2) shows similar PUMA expression profile in both human and mouse cell lines detected by two independent anti-PUMA antibodies that recognize different epitopes, 3041 against C-terminus and 3043 against the N-terminus. PUMA proteins are detected in most of the cell lines with different expression levels by the two independent antibodies.
siRNA Knockdown Validation (Figure 3): Anti-PUMA antibody (3041) specificity was further verified by PUMA specific siRNA knockdown. PUMA signal in HeLa cells transfected with PUMA siRNAs was much weaker in comparison with that in HeLa cells transfected with control siRNAs.
- ISOFORMS: Human PUMA has 4 isoforms, including isoform 1 (193aa, 21kD), isoform 2 (131aa, 14kD), isoform 3 (101aa, 10kD) and isofrom 4 (261aa, 27kD). This antibody detects human isoform 1&2, mouse and rat PUMA (193aa, 21kD for both of them).

- PUMA Antibody: Apoptosis is related to many diseases and development. The p53 tumor-suppressor protein induces apoptosis through transcriptional activation of several genes. A novel p53 inducible pro-apoptotic gene was identified recently and designated PUMA (for p53 upregulated modulator of apoptosis) and bbc3 (for Bcl-2 binding component 3) in human and mouse. PUMA/bbc3 is one of the pro-apoptotic Bcl-2 family members including Bax and Noxa, which are also transcriptional targets of p53 (1). The PUMA gene encodes two BH3 domain-containing proteins termed PUMA-alpha and PUMA-beta (2). 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.
