Tracking the PUMA: How ProSci’s Antibodies are Pouncing on Cancer Research

Learn about the role of PUMA in apoptosis and cancer and how ProSci’s PUMA antibodies can aid in the study of its relationship to p53.

What is the PUMA Protein?

PUMA, also known as the p53 upregulated modulator of apoptosis, is a protein that belongs to the BCL-2 family of proteins.

It plays a critical role in the regulation of cell death and cancer development. PUMA is a pro-apoptotic protein that is activated in response to DNA damage and other cellular stress signals.

It is known to bind to and inhibit anti-apoptotic Bcl-2 proteins (Bax & Bak), thereby promoting the activation of the intrinsic apoptotic pathway. PUMA has been found to be up-regulated in a variety of cancers due to oncogenic stress, oxidative stress, and DNA damage (to name a few),(2) making it an attractive target for cancer therapy.

Why is PUMA Research Important?

The study of PUMA has gained significant attention in recent years, particularly in the field of cancer research and in mitophagy and autophagy research. The ability to accurately detect and measure PUMA levels in cells and tissues is crucial for understanding its role in cell death and its relationship to p53.

Highly Validated PUMA Antibodies from ProSci

To track and measure levels of expressed PUMA in cells, antibodies are regularly used in applications from western blot, ICC, IF, and ELISA. Of these antibodies, two popular tools used among researchers with more than 90 citations are ProSci’s PUMA rabbit polyclonal antibodies (Cat No. 3041 & Cat No. 3043).

These antibody preparations have been validated for western blot, ELISA, immunocytochemistry, and immunofluorescence. They have been used in various studies to detect PUMA expression in cell lines and in primary tissues, including cancer cell lines and normal tissues.

ProSci PUMA Antibodies: A Research Tool for Scientists

ProSci’s PUMA antibodies have been cited in many research articles in high-impact journals such as Cell Death & Disease, Journal of Neurotrauma, Frontiers in Cellular Neuroscience, and many more.

This shows how reliable and high-quality the ProSci’s PUMA antibodies are, which have become a valuable tool for researchers studying the role of PUMA in cell death and its relationship to p53.

Below are some recent studies where the antibodies have been used:

  • Sabirzhanov B, Matyas J, Coll-Miro M, Yu LL, Faden AI, Stoica BA, Wu J.
