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