Summary:
Purpose
Our Quick Step Human Retinol binding protein 4,RBP-4 ELISA Kit is to assay RBP-4 levels in Human serum, plasma, culture media or any biological fluid.
Principle
This ELISA kit uses Sandwich-ELISA as the method. The Microplate provided in this kit has been pre-coated with an antibody specific to RBP-4, make it to solid-phase antibody.Samples are added to the Microplate wells and combined to the specific antibody. Then a Horseradish Peroxidase (HRP)-conjugated antibody specific for RBP-4 is added to each Microplate well and incubated,so the antibody-antigen-Enzyme labeled antibody complex is formed.Following a wash to remove any unbound reagent,then the TMB substrate solution is added to each well. Only those wells that contain RBP-4 and HRP conjugated RBP-4 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 qualitative determination of RBP-4 is determined by comparing with the CUT OFF value.
Typical Data
The standard curve of QS1534Hu is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
