REAGEN^™Sulfonamide ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Sulfonamide in eggs, fish, shrimp, meat (beef, chicken and pork), honey, milk, milk powder.

The unique features of the kit are:

• Rapid extraction method for various samples with high recovery (80-105%).
• High sensitivity (0.2 ppb).
• High reproducibility.
• A quick ELISA assay (less than 1 hours regardless of number of samples).

Procedure Overview

The method is based on a competitive colorimetric ELISA assay. The drug of interest has been coated in the plate wells. During the analysis, sample and the Sulfonamide antibody are added along with secondary antibody, tagged with a peroxidase enzyme. If the drug residue is present in the sample, it will compete for the Sulfonamide antibody, thereby preventing the antibody from binding to the drug attached to the well. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the drug residue concentration in the sample.
