Human GZMH(Granzyme H) ELISA Kit

Cytotoxic chymotrypsin-like serine protease with preference for bulky and aromatic residues at the P1 position and acidic residues at the P3' and P4' sites. Probably necessary for target cell lysis in cell-mediated immune responses. Participates in the antiviral response via direct cleavage of several proteins essential for viral replication Assay Type: Sandwich. Sensitivity: 6.1 pg/mL. Standard: 1000 pg/mL. Detection range: 15.63-1000 pg/mL. Sample type: Serum, plasma, tissue homogenates, cell lysates and other biological fluids.. Assay length: 3.5h. Research Field: Enzyme & Kinase,. Test principle: 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 GZMH. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human GZMH. 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 GZMH, 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 GZMH in the samples is then determined by comparing the OD of the samples to the standard curve.
