Anti-RAD9A Antibody

This unconjugated mouse monoclonal antibody targets RAD9A, a checkpoint exonuclease recruited to stalled replication forks and DNA double-strand breaks through the RAD9-RAD1-HUS1 (9-1-1) sliding clamp complex. It is validated for Western blot and immunoprecipitation workflows and recognizes the human, mouse, rat, and monkey orthologs, enabling comparative studies across standard model systems. The reagent is supplied as a 100 µl liquid aliquot of IgG2b, pairs with common anti-mouse secondary antibodies, and is appropriate for chromatin fraction analyses and co-immunoprecipitation of 9-1-1 complex partners. Researchers using Antibodies.com reagents apply this clone to investigate S-phase checkpoint signaling, ATR-dependent phosphorylation, and the contribution of RAD9A to cellular genotoxic stress responses.
