Product Detail
Company Profile

Replication protein A (RPA) is a 3-subunit single-stranded DNA (ssDNA)-binding protein that has been isolated from human cells and found to be essential for in vitro replication of the papovavirus SV40. The human cDNA directed production in E. coli of a 70-kD protein that reacted with a monoclonal antibody directed against the 70-kD subunit of the human protein. The recombinant subunit, purified from bacteria, exhibited single-stranded DNA-binding activity comparable to that of the complete RPA complex. It could substitute for the complete complex in stimulating the activity of DNA polymerase alpha-primase, but could not substitute for the complete complex in SV40 DNA replication in vitro, suggesting an important functional role for the other subunits.

Rat Replication protein A 70 kDa DNA-binding subunit (RPA1) ELISA Kit employs a two-site sandwich ELISA to quantitate RPA1 in samples. An antibody specific for RPA1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRPA1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for RPA1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RPA1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
