Estriol ELISA Test Kit,specification,price,image-Bio-Equip in China

1. 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.
