Drug Names

Generic Name: Canine Carbonhydrate Antigen 19-9 (CA19-9)ELISA Kit

Purpose

Our Canine Carbonhydrate Antigen 19-9 (CA19-9)ELISA kit is to assay CA19-9 levels in Canine 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 CA19-9. 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 CA19-9 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 CA19-9 and HRP conjugated CA19-9 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 CA19-9. You can calculate the concentration of CA19-9 in the samples by comparing the OD of the samples to the standard curve.
