TMPRSS2 ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level TMPRSS2 were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level TMPRSS2 were tested on 3 different plates, 8 replicates in each plate. Intra-Assay: CV Inter-Assay: CV Inter-Assay: CV Inter-Assay: CV

Serine protease that proteolytically cleaves and activates the viral spike glycoproteins which facilitate virus-cell membrane fusions; spike proteins are synthesized and maintained in precursor intermediate folding states and proteolysis permits the refolding and energy release required to create stable virus-cell linkages and membrane coalescence. Facilitates human SARS coronavirus (SARS-CoV) infection via two independent mechanisms, proteolytic cleavage of ACE2, which might promote viral uptake, and cleavage of coronavirus spike glycoprotein which activates the glycoprotein for cathepsin L-independent host cell entry. Proteolytically cleaves and activates the spike glycoproteins of human coronavirus 229E (HCoV-229E) and human coronavirus EMC (HCoV-EMC) and the fusion glycoproteins F0 of Sendai virus (SeV), human metapneumovirus (HMPV), human parainfluenza 1, 2, 3, 4a and 4b viruses (HPIV) . Essential for spread and pathogenesis of influenza A virus (strains H1N1, H3N2 and H7N9) ; involved in proteolytic cleavage and activation of hemagglutinin (HA) protein which is essential for viral infectivity.

Aviva Systems Biology TMPRSS2 ELISA Kit (Human) (OKDD00567) is based on standard sandwich enzyme-linked immuno-sorbent assay methodology. An antibody for TMPRSS2 has been pre-coated onto a 96-wellplate (12 x 8 Well Strips) . Standards or test samples are added to the wells, incubated and removed. A biotinylated detector antibody specific for TMPRSS2 is added, incubated and removed. Avidin-Peroxidase Conjugate is then added, incubated and unbound conjugate is washed away. An enzymatic reaction is produced through the addition of TMB substrate which is catalyzed by HRP generating a blue color product that changes yellow after adding acidic stop solution. The density of yellow coloration read by absorbance at 450 nm and is quantitatively proportional to the amount of sample TMPRSS2 captured in well.
