Summary:

 

Purpose

 

Our Quick Step Human Stromal cell derived factor 1beta,SDF-1beta ELISA kit is to assay SDF-1beta 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 SDF-1beta. 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 SDF-1beta 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 SDF-1beta and HRP conjugated SDF-1beta 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 450 nm. The OD value is proportional to the concentration of SDF-1beta. You can calculate the concentration of SDF-1beta in the samples by comparing the OD of the samples to the standard curve.

 

Typical Data

 

The standard curve of QS1648Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
