Summary:
Purpose
Our Quick Step Rat Chemokine (C-X-C Motif) Ligand 5 (CXCL5)ELISA Kit is to assay CXCL5 levels in Rat 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 CXCL5. 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 CXCL5 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 CXCL5 and HRP conjugated CXCL5 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 CXCL5. You can calculate the concentration of CXCL5 in the samples by comparing the OD of the samples to the standard curve.
Typical Data
The standard curve of QS1895Ra is provided for demonstration only. A standard curve should be generated for each set of samples assayed.
