Human MCT (Mast Cell Tryptase) Microsample ELISA Kit

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human MCT. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human MCT. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human MCT, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human MCT in the samples is then determined by comparing the OD of the samples to the standard curve.Detection Range: 1.57-100 ng/mL. Sensitivity: 0.55 ng/mL. Assay Type: Sandwich. Standard: 100 ng/mL. Sample Type: sserum, plasma, tissue homogenates. Assay duration: 3.5h. Protein Function: Tryptase is the major neutral protease present in mast cells and is secreted upon the coupled activation-degranulation response of this cell type. May play a role in innate immunity. Isoform 2 cleaves large substrates, such as fibronectin, more efficiently than isoform 1, but seems less efficient toward small substrates (PubMed:18854315) [The Uniprot Consortium]
