Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate PRSS16 in samples. An antibody specific for PRSS16 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPRSS16 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PRSS16 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 PRSS16 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:TSSP is thought to play a role in the alternative antigen presenting pathway used by cortical thymic epithelial cells during the positive selection of T cells. The gene is found in the large histone gene cluster on chromosome 6, near the major histocompatibility complex (MHC) class I region. A second transcript variant has been described, but its full length nature has not been determined.The deduced 514-amino acid PRSS16 protein, which the authors termed TSSP, has a calculated molecular mass of 55 kD. PRSS16 contains a putative N-terminal signal peptide and a prolylendopeptidase consensus sequence. Within its 3-prime untranslated region, it has 2 different polyadenylation sites. PRSS16 shares sequence similarity with prolylcarboxypeptidase (PRCP), particularly around the active-site serine.
