Summary:

 

Purpose

 

Our Quick Step Porcine plasminogen activator inhibitor 1,PAI-1 ELISA Kit is to assay PAI-1 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 antibody specific to PAI-1. 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 PAI-1 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 PAI-1 and HRP conjugated PAI-1 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 PAI-1. You can calculate the concentration of PAI-1 in the samples by comparing the OD of the samples to the standard curve.

 

Typical Data

 

The standard curve of QS0119Po is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
