General Description of RPA/p34 .
This antibody reacts with a 32-34 kDa protein known as replication protein A (RPA). RPA is involved in DNA replication, repair and recombination. Human RPA is a stable heterotrimer of 70 kDa, 32-34 kDa and 11-14 kDa subunits (RPA70, RPA32 and RPA14 respectively). RPA is required for the SV40 large tumor antigen-catalyzed unwinding for SV40 DNA and stimulates DNA polymerase alpha and δ.

RPA/p34 Information for Pathologists

Common Uses By Pathologists:

RPA/p34 is expressed in most cancer cells. It exhibits moderate to strong nuclear staining with additional cytoplasmic positivity in a few cases. Liver cancers showed generally strong immunoreactivity in cholangiocarcinomas. Weaker staining was observed in hepatocellular cancers compared to other malignancies.

Limitations and Warranty
