Diethylstilbestrol Elisa Test Kit - China

price: contact company for price

1. Principle

The BIOKAU® Diethylstilbestrol ELISA 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.
