1. Principle
Tilmicosin ELISA kit is a competitive enzyme immunoassay for the quantitative analysis of Tilmicosin in milk, honey, tissue and serum.
The coupling antigens are coated on the micro-well stripes. The Tilmicosin in the sample and the coupling antigens coated on the micro-well stripes compete for the anti-Tilmicosin 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 Tilmicosin in it. The measurement is made photometrically at 450 nm. The absorption is inversely proportional to the Tilmicosin concentration in the sample.
