Product Description

Purpose

Our Quick Step Human Cystatin C,Cys-C ELISA Kit is to assay Cys-C levels in Human serum, plasma, culture media or any biological fluid.


Principle

 
This ELISA kit uses Sandwich-ELISA as the method. The Microelisa stripplate provided in this kit has been pre-coated with an antibody specific to Cys-C. Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)- conjugated antibody specific for Cys-C is added to each Microelisa stripplate well and incubated. Free components are washed away. The TMB substrate solution is added to each well. Only those wells that contain Cys-C and HRP conjugated Cys-C antibody will appear blue in color and then turn yellow after the addition of the stop solution. The optical density (OD) is measured spectrophotometrically at a wavelength of **0 nm. The OD value is proportional to the concentration of Cys-C. You can calculate the concentration of Cys-C in the samples by comparing the OD of the samples to the standard curve.

Typical Data

The standard curve of QS***5Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
