SERPIND1 ELISA Kit (Mouse)

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

AA985900; AI303446; HC; Hcf2; HCII; HC-II; heparin cofactor 2; heparin cofactor II; protease inhibitor leuserpin-2; serine (or cysteine) proteinase inhibitor, clade D (heparin cofactor), member 1; serpin D1.

Thrombin inhibitor activated by the glycosaminoglycans, heparin or dermatan sulfate. In the presence of the latter, HC-II becomes the predominant thrombin inhibitor in place of antithrombin III (AT) . Also inhibits chymotrypsin, but in a glycosaminoglycan-independent manner.

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