PUMA Antibody

PUMA Antibody

Catalog# : 3041

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 (1-3). PUMA/bbc3 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-alpha and PUMA-beta (1). 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.

Additional Names : PUMA (CT), bbc3
Description
Left: Western blot analysis of PUMA expression in human (H) K562 and mouse (M) 3T3 cell lysates with PUMA antibody at 2 µg/ml

Other Product Images
Source : PUMA antibody was raised against a synthetic peptide corresponding to 14 amino acids near the carboxy terminus of human PUMA-a (GenBank Accession number Q9BXH1) This sequence is identical between a and b forms of the PUMA proteins.

Purification : Affinity chromatography purified via peptide column

Clonality and Clone : This is a polyclonal antibody.

Host : PUMA antibody was raised in rabbit. Please use anti-rabbit secondary antibodies.

Immunogen : Human PUMA (C-Terminus) Peptide (Cat. No. 3041P)

Application : PUMA antibody can be used for detection of PUMA by Western blot at 1 to 2 µg/ml.K562 or 3T3 cell lysate can be used as a positive control and a band at approximately 23 kDa can be detected. A lower band at approximately 16 kDa was detected in MOLT4 and U937 cells, which may represent the PUMA-b form. It is human and mouse reactive.

Tested Application(s) : E, WB, ICC

Buffer : Antibody is supplied in PBS containing 0.02% sodium azide.

Blocking Peptide : Cat. No. 3041P - PUMA Peptide

Long-Term Storage : PUMA antibody can be stored at 4ºC, stable for one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
