  • 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.
