Anti-RPA3 Antibody

RPA3 (Replication Protein A3) is the smallest 14 kDa subunit of the heterotrimeric single-stranded DNA-binding RPA complex that shields ssDNA intermediates generated during DNA replication, repair, and recombination. This Rabbit polyclonal antibody from Antibodies.com is raised against full-length or recombinant human RPA3 and is supplied as a 100 µl vial at 1 mg/ml in PBS with 0.1% sodium azide and 50% glycerol. The unconjugated polyclonal reagent recognizes multiple epitopes across the target protein, allowing strong signal in Western blot (WB) and immunohistochemistry (IHC) on human tissue and cell preparations. It is validated for detection of endogenous RPA3 in lysates and formalin-fixed paraffin-embedded sections, supporting studies of genome stability, replication stress, and the DNA damage response. The 50% glycerol cryoprotectant reduces loss from occasional freeze-thaw events; aliquot upon first thaw and refrigerate for routine use. Intended for research use only.
