The RPA2 Polyclonal Antibody (CAB24881) is a high-quality antibody developed for reliable detection and analysis of target proteins. RPA (Replication Protein A) is required for DNA recombination, repair, and replication, with its activity mediated through single-stranded DNA binding and protein interactions. As a component of the alternative RPA complex (aRPA), it supports DNA polymerase delta synthesis and participates in nucleotide excision repair and RAD51-dependent strand exchange, though it does not support chromosomal DNA replication.
This antibody is validated for use in WB, IHC-P, IF/ICC, ELISA applications and has demonstrated reactivity against Human samples.

Required for DNA recombination, repair and replication. The activity of RP-A is mediated by single-stranded DNA binding and protein interactions.
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.
