Summary:

 

Purpose

 

Our Quick Step Human Tissue type plasminogen activator (t-PA)elisa Kit is to assay t-PA 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 t-PA. 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 t-PA 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 t-PA and HRP conjugated t-PA 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 t-PA. You can calculate the concentration of t-PA in the samples by comparing the OD of the samples to the standard curve.

 

Typical Data

 

The standard curve of QS3885Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
