The Phospho-p53-S33 Antibody (CABP0762) is a high-quality antibody developed for reliable detection and analysis of target proteins. This antibody, raised in rabbits, is highly specific for detecting phosphorylation of TP53 at serine 33 in human samples, and has been validated for use in Western blot applications.Phosphorylation of TP53 at serine 33 is known to regulate its activity and stability, influencing its ability to induce cell cycle arrest, apoptosis, and DNA repair in response to cellular stress. The Phospho-TP53 (S33) Polyclonal Antibody enables researchers to study the phosphorylation status of TP53 in various cell types, providing valuable insights into the mechanisms of TP53-mediated tumorigenesis and potential therapeutic strategies targeting this pathway.
This antibody is validated for use in WB, IHC-P, IP, ELISA applications and has demonstrated reactivity against Human, Mouse, Rat samples.

This gene encodes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. The encoded protein responds to diverse cellular stresses to regulate expression of target genes, thereby inducing cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. Mutations in this gene are associated with a variety of human cancers, including hereditary cancers such as Li-Fraumeni syndrome. Alternative splicing of this gene and the use of alternate promoters result in multiple transcript variants and isoforms. Additional isoforms have also been shown to result from the use of alternate translation initiation codons from identical transcript variants (PMIDs: 12032546, 20937277).
