Sulfamethoxydiazine (SMD) ELISA Test Kit

 Principle

This test kit is based on the competitive enzyme immunoassay for the detection of Sulfamethoxy-diazine in the sample. The coupling antigens is pre-coated on the micro-well stripes. The Sulfamethoxydiazine in the sample and the coupling 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 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.
