Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate SAP130 in samples. An antibody specific for SAP130 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySAP130 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SAP130 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 SAP130 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:SF3B3 encodes subunit 3 of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron's branch site in a sequence independent manner and may anchor the U2 snRNP to the pre-mRNA. Splicing factor 3b is also a component of the minor U12-type spliceosome. Subunit 3 has also been identified as a component of the STAGA (SPT3-TAF(II)31-GCN5L acetylase) transcription coactivator-HAT (histone acetyltransferase) complex, and the TFTC (TATA-binding-protein-free TAF(II)-containing complex). These complexes may function in chromatin modification, transcription, splicing, and DNA repair.
