Application Abreviews Notes
IHC-P 1/100 - 1/500. Antigen retrieval is not essential but may optimise staining. Antigen retrieval with tris-EDTA buffer pH 9.0 recommended. Likely to work with frozen sections.
ICC/IF Use at an assay dependent concentration. PubMed: 21079677


  • Function
    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.
    Functions as component of the alternative replication protein A complex (aRPA). aRPA binds single-stranded DNA and probably plays a role in DNA repair; it does not support chromosomal DNA replication and cell cycle progression through S-phase. In vitro, aRPA cannot promote efficient priming by DNA polymerase alpha but supports DNA polymerase delta synthesis in the presence of PCNA and replication factor C (RFC), the dual incision/excision reaction of nucleotide excision repair and RAD51-dependent strand exchange.
  • Sequence similarities
    Belongs to the replication factor A protein 1 family.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
    Sumoylated on lysine residues Lys-449 and Lys-577, with Lys-449 being the major site. Sumoylation promotes recruitment of RAD51 to the DNA damage foci to initiate DNA repair through homologous recombinaison. Desumoylated by SENP6.
