Summary:
Purpose
Our Quick Step Porcine circovirus type Ⅱ antibody (PCVⅡ-Ab)elisa Kit is to assay PCVⅡ-Ab levels in Porcine 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 antigen specific to PCVⅡ-Ab. Standards or samples are added to the appropriate Microelisa stripplate wells and combined to the specific antigen. Then a Horseradish Peroxidase (HRP)- conjugated antigen specific for PCVⅡ-Ab 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 PCVⅡ-Ab and HRP conjugated PCVⅡ-Ab antigen 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 PCVⅡ-Ab. You can calculate the concentration of PCVⅡ-Ab in the samples by comparing the OD of the samples to the standard curve.
Typical Data
The standard curve of QS0206Po is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
