Anti-RPA2 Antibody

This unconjugated rabbit polyclonal reagent from Antibodies.com targets RPA2 (Replication Protein A2), the ~32 kDa subunit of the heterotrimeric single-stranded DNA-binding complex that shields exposed ssDNA during DNA replication, repair, and recombination. In published studies, RPA2 phosphorylation on serine residues is widely used as a marker of replication stress and checkpoint activation in the DNA damage response.

Supplied as a 100 µl liquid aliquot, the antibody has been validated for western blot, immunohistochemistry, and immunofluorescence workflows on human, mouse, and rat samples. Host species is rabbit, clonality is polyclonal, and the conjugate status is unconjugated, so users can pair it with a secondary reagent of their choice for either fluorescent or chromogenic readout.

Common research settings include probing replication fork stability, ATR signaling, and homologous recombination in cultured cells or fixed tissue sections. Aliquot the reagent on receipt and store refrigerated to preserve activity through repeated freeze-thaw cycles during longer-term storage.
