1. Principle

This test kit is based on the competitive enzyme immunoassay for the detection of Sulfamethoxydiazine in the chicken, pork, milk, serum,liver, honey and egg. The conjugated antigens is pre-coated on the micro-well stripes. The Sulfamethoxydiazine in the sample and the conjugate antigens pre-coated on the micro-well stripes compete for the anti- Sulfamethoxydiazine antibodies. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the testing sample has a negative correlation with the Sulfamethoxydiazine residues concentration in the sample. This value is compared to the standard curve and Sulfamethoxydiazine concentration is subsequently obtained.
