Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PRIM1 in samples. An antibody specific for PRIM1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRIM1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRIM1 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 PRIM1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The replication of DNA in eukaryotic cells is carried out by a complex chromosomal replication apparatus, in which DNA polymerase alpha and primase are two key enzymatic components. Primase, which is a heterodimer of a small subunit and a large subunit, synthesizes small RNA primers for the Okazaki fragments made during discontinuous DNA replication. The protein encoded by this gene is the small, 49 kDa primase subunit. The DNA polymerase-alpha/primase complex contains 4 subunits: the polymerase-alpha p180 (POLA) and p68 (POLA2) subunits, and the primase p58 (PRIM2A) and p49 (PRIM1) subunits. Primase synthesizes oligoribonucleotides that serve as primers for the initiation of DNA synthesis. It plays a role in both the initiation of DNA replication and the synthesis of Okazaki fragments for lagging strand synthesis
