Rabbit anti PUMA antibody
recognizes the p53 - upregulated modulator of apoptosis, also known as Bcl-2 binding component 3, JFY-1 or Bcl-2. PUMA is a 193 amino acid ~20 kDa pro-apoptotic member of the BCL-2 family.
Bcl-2 binding component 3 is localized to the mitochondria, binds BCL-2 and induces cytochrome C release and apoptosis in response to p53 (Follis et al. 2013
). Four isoforms of PUMA have been described due to alternative splicing. Rabbit anti PUMA antibody is expected to recognize the canonical isoform 1, also known as PUMA alpha, it is not expected to recognize any of the other isoforms of PUMA.

- This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.
Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.

Applications of PUMA antibody
|Immunohistology - Paraffin 1
- 1This product requires antigen retrieval using heat treatment prior to staining of paraffin sections.Sodium citrate buffer pH 6.0 is recommended for this purpose.
Where this antibody has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the antibody for use in their own system using appropriate negative/positive controls.
