Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PRPF6 in samples. An antibody specific for PRPF6 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRPF6 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRPF6 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 PRPF6 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:PRP6 appears to be involved in pre-mRNA splicing, possibly acting as a bridging factor between U5 and U4/U6 snRNPs in formation of the spliceosome. The encoded protein also can bind androgen receptor, providing a link between transcriptional activation and splicing. Predicted amino acid sequence of the protein is similar to those of yeast splicing factors, Prp1p/Zer1p of Schizosaccharomyces pombe and Prp6p of Saccharomyces cerevisiae. Among these proteins, tetratrico peptide repeat (TPR) motif, which mediates protein-protein interactions, is conserved, whereas leucine zipper motif is found only in the 100-kDa protein. Indirect immunofluorescent staining showed that the 100-kDa protein localized in the nucleus in HeLa cells.
