Anti-RPA4 Antibody

This rabbit polyclonal antibody targets RPA4, a divergent subunit of the heterotrimeric Replication Protein A (RPA) single-stranded DNA-binding complex that supports DNA replication, repair, recombination, and checkpoint signaling. Supplied at 1 mg/ml in phosphate buffered saline (PBS) with 15 mM sodium azide at approximately pH 7.2, this unconjugated primary reagent is validated for Western Blot detection across human, mouse, and rat samples. Each vial delivers 100 µl of antibody, supporting studies of replication stress, the DNA damage response, and meiotic recombination in which RPA4 expression has been characterized. Researchers working on cancer cell biology and genome maintenance pathways can apply this reagent to investigate alternative RPA complex composition in transformed cells. Compatible with standard immunoblotting workflows, the antibody is shipped refrigerated; aliquoting upon arrival preserves stability across repeated experiments. Antibodies.com offers the product for research use only, providing a focused tool for laboratories examining single-stranded DNA processing and the cellular response to genotoxic stress.
