Summary:
Purpose
Our Quick Step Human Dipeptidyl Peptidase (DPP)elisa Kit is to assay ITGA2/CD49b 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 ITGA2/CD49b. 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 ITGA2/CD49b 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 ITGA2/CD49b and HRP conjugated ITGA2/CD49b 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 ITGA2/CD49b. You can calculate the concentration of ITGA2/CD49b in the samples by comparing the OD of the samples to the standard curve.
Typical Data
The standard curve of QS3546Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
