Anti-RPA3 Antibody

Raised in rabbit against the p14 subunit of the Replication Protein A (RPA) heterotrimer, this unconjugated polyclonal IgG antibody from Antibodies.com binds RPA3, a single-stranded DNA-binding protein that supports DNA replication, nucleotide excision repair, and the DNA damage response. The reagent is supplied as 50 µl and is validated for Western blot and immunofluorescence detection in human, mouse, and rat samples. Researchers studying replication fork stability, checkpoint activation (such as ATR/Chk1 signaling), or genome maintenance often use RPA3-specific reagents to monitor complex loading at stalled forks and resection sites. Aliquoting upon arrival and storage at -20 °C preserves antibody activity across multiple freeze-thaw cycles, while the unconjugated format permits pairing with HRP-conjugated or fluorescent secondary antibodies chosen by the user.
