Estriol ELISA Test Kit

Principle

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

Sample performance: detect Estriol residue in animal tissue and aquatic tissue(meat/liver)
