Western Blot (WB)
(Western blot analysis of RPA70 expression in HELA whole cell lysates (lane 1), JURKAT whole cell lysates (lane 2) and COLO320 whole cell lysates (lane 3). RPA70 at 70KD was detected using rabbit anti- RPA70 Antigen Affinity purified polyclonal antibody at0.5 ug/mL. The blot was developed using chemiluminescence (ECL) method. )

Background: Replication protein A 70 kDa DNA-binding subunit is a protein that in humans is encoded by the RPA1 gene. This gene is mapped to chromosome 17p13.3. Replication protein A (RPA) is a heterotrimeric single-strand DNA (ssDNA)-binding protein essential for DNA replication, repair, and recombination. It is composed of 70-kD (RPA1), 32-kD (RPA2), and 14-kD (RPA3) subunits. The RPA1 subunit is responsible for high-affinity ssDNA binding. The RPA complex was originally isolated as a factor essential for in vitro replication of the papovavirus SV40. It had been found that recombinant human RPA1, purified from bacteria, exhibited ssDNA-binding activity comparable to that of the complete RPA complex. RPA1 could substitute for the complete complex in stimulating the activity of DNA polymerase alpha-primase, but it could not substitute for the complete complex in SV40 DNA replication in vitro, suggesting an important functional role for the other subunits.
NCBI and Uniprot Product Information
Uniprot Description
RPA1: Plays an essential role in several cellular processes in DNA metabolism including replication, recombination and DNA repair. Binds and subsequently stabilizes single-stranded DNA intermediates and thus prevents complementary DNA from reannealing. Heterotrimer composed of RPA1, RPA2 and RPA3 (canonical replication protein A complex). Component of the alternative replication protein A complex (aRPA) composed of RPA1, RPA3 and RPA4. The DNA-binding activity may reside exclusively on the RPA1 subunit. Interacts with RIPK1 and XPA. Interacts with RPA4. Interacts with the polymerase alpha subunit POLA1/p180; this interaction stabilizes the replicative complex and reduces the misincorporation rate of DNA polymerase alpha by acting as a fidelity clamp. Interact with RAD51 and SENP6 to regulate DNA repair. Interacts with HELB; this interaction promotes HELB recruitement to chromatin following DNA damage. Belongs to the replication factor A protein 1 family.

Product Notes
The RPA70 rpa1 (Catalog #AAA177992) is an Antibody and is intended for research purposes only. The product is available for immediate purchase. The Anti-RPA70 Antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's RPA70 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Western Blot Concentration: 0.1-0.5ug/ml. Researchers should empirically determine the suitability of the RPA70 rpa1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "RPA70, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
