Summary:

 

Purpose

 

Our Quick Step Human D-lactate ELISA kit is to assay D-lactate 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 D-lactate. 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 D-lactate 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 D-lactate and HRP conjugated D-lactate 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 D-lactate. You can calculate the concentration of D-lactate in the samples by comparing the OD of the samples to the standard curve.

 

Typical Data

 

The standard curve of QS2998Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
