Anti-PCNA Antibody

This unconjugated mouse monoclonal IgG2b reagent targets Proliferating Cell Nuclear Antigen (PCNA), a processivity factor for DNA polymerase delta that is widely used as a marker of S-phase entry and active cell proliferation.

Distributed by Antibodies.com, the antibody is supplied at 100 µl per vial and is validated across four species (human, mouse, rat, and monkey) for western blot, immunoprecipitation, immunocytochemistry, and immunohistochemistry applications.

In research settings, the reagent is routinely used to identify proliferating cells in tumor sections, evaluate regenerative responses in tissue injury models, and confirm replication status in stem cell and developmental biology studies. The unconjugated format allows end users to pair it with their preferred secondary detection reagents, fluorescent dyes, or enzymatic reporters depending on the experimental platform.
