Recombinant Human RPA2 Protein

Product Name: Recombinant Human RPA2 Protein
Catalog #:  hRP-0770
Manufacture:  LD Biopharma, Inc.

The RPA complex, consisted of three subunits of RPA1, RPA2 and RPA3 (70, 34 and 11 kDa, respectively), has been identified as a cellular factor that plays an essential role in SV40 DNA replication in vitro. It has been shown that RPA plays roles in the DNA transactions of DNA replication, transcription and recombination in eukaryotic cells by interacting with single-stranded DNA. Recently, human replication protein A 32 kDa subunit (RPA2) has been identified for interaction with many DNA replication key factors, and involved in various cancer developments.

Full-length human RPA2 (270aa) gene was constructed with 15aa N-terminal T7 tag and expressed in E.coli as inclusion bodies, refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
