Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PRTFDC1 in samples. An antibody specific for PRTFDC1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRTFDC1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRTFDC1 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 PRTFDC1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The predicted PRTFDC1 protein contains a phosphoribosyl transferase domain, but it lacks conservation of 11 HPRT1 residues critical for HPRT function, suggesting that PRTFDC1 has lost its ancestral HPRT activity. Database analysis revealed that Prtfdc1 is present in several vertebrate species. However, in mouse, the Prtfdc1 gene appeared to be inactive due to 3 independent mutations.
PRTFDC1was inactivated either by deletion or hypermethylation in a significant subset of oral squamous cell carcinomas. Restoration of PRTFDC1 expression in 1 of these lines inhibited cell growth in colony formation assays, whereas knockdown of PRTFDC1 expression in PRTFDC1-expressing cells promoted cell growth.
