Anti-RPA3 Antibody

RPA3 (Replication Protein A3) is the smallest subunit of the heterotrimeric RPA complex, a single-stranded DNA-binding protein essential for DNA replication, repair, and recombination. The polyclonal antibody from Antibodies.com is raised in rabbit and selectively targets the human RPA3 protein, with verified reactivity across mouse and rat samples. Supplied as an unconjugated IgG preparation in a 200 µl vial, the reagent is validated for western blot and immunofluorescence workflows, making it a practical choice for laboratories studying genome stability, the DNA damage response, and cell cycle checkpoint signaling. Researchers can apply it to detect endogenous RPA3 in cell lysates by western blot or to localize the protein within fixed cells and tissue sections via immunofluorescence staining. The polyclonal format provides recognition of multiple epitopes on the RPA3 subunit, which can improve signal consistency across experimental conditions.
