Ractopamine ELISA Test Kit
Catalog No. LSY-10013
1. Principle
The test kit is based on the competitive enzyme immunoassay for the detection of Ractopamine in the sample. The conjugated antigens is pre-coated on the micro-well stripes. The Ractopamine in the sample and the coupling antigens pre-coated on the micro-well stripes compete for anti-Ractopamine 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 Ractopamine concentration in the sample. The value is compared to the standard curve and the Ractopamine concentration is subsequently obtained.
