CTSZ ELISA Kit (Human)

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Cathepsin Z (CTSZ) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Cathepsin Z (CTSZ) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

Carboxypeptidase LB; cathepsin B2; cathepsin IV; cathepsin P; cathepsin X; cathepsin Y; cathepsin Z; cathepsin Z1; CTSX; cysteine-type carboxypeptidase; lysosomal carboxypeptidase B; preprocathepsin P.

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 Cathepsin Z (CTSZ) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Cathepsin Z (CTSZ) . 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 Cathepsin Z (CTSZ), 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 Cathepsin Z (CTSZ) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
