Elabscience Human PCT[Procalcitonin] Elisa Kit

Intended use

This Elisa kit applies to the in vitro quantitative determination of Human PCT concentrations in serum, plasma and other biological fluids.

Test principle

This Elisa kit uses the Sandwich-Elisa principle. The micro Elisa plate provided in this kit has been pre-coated with an antibody specific to Human PCT. Samples (or Standards) are added to the micro Elisa plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human PCT and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PCT, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 ± 2 nm. The OD value is proportional to the concentration of Human PCT. You can calculate the concentration of Human PCT in the samples by comparing the OD of the samples to the standard curve.
