Sulfadiazine(SDZ) ELISA Test Kit

Catalog No. LSY-10055

1. Principle

This test kit is based on the competitive enzyme immunoassay for the detection of Sulfadiazine residue. The coupling antigens are pre-coated on the micro-well stripes. The Sulfadiazine in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-Sulfadiazine 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 Sulfadiazine in the sample. This value is compared to the standard curve and the Sulfadiazine concentration is subsequently obtained.
