Anti-PIG3 Antibody

The Antibodies.com anti-PIG3 polyclonal antibody targets the p53-induced gene 3 protein, also known as TP53I3, a NADPH-dependent oxidoreductase implicated in cellular oxidative stress response and reactive oxygen species homeostasis. This unconjugated rabbit polyclonal reagent is supplied as 100 µL aliquots and supports Western blot, immunohistochemistry, and immunofluorescence workflows on human sample material. The antibody enables visualization of endogenous PIG3 expression in fixed tissue sections and cultured cell preparations, supporting studies of p53-mediated transcriptional signaling, DNA damage response pathways, and tumor suppressor biology. Researchers apply this reagent to investigate apoptosis regulation, oxidative stress markers, and the downstream gene programs activated by p53 in cancer models and stress challenge experiments.
