Diethylstilbestrol Des Elisa Test Kit - China

Diethylstilbestrol ELISA Test Kit

Catalog No.

LSY-10022

1 - Principle

This test kit is based on the competitive enzyme immunoassay for the detection of Diethylstilbestrol(DES) in the feed, urine, liver, meat, shrimp and fish.

The conjugate antigen is pre-coated on the micro-well stripes.

The Diethylstilbestrol in the sample competes with the conjugate antigen pre-coated on the micro-well stripes, to interact with the antibodies against Diethylstilbestrol.

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 content of Diethylstilbestrol in the sample.

This value is compared to the standard curve and the content of the corresponding Diethylstilbestrol is subsequently obtained.
