    1. Principle

    The BIOKAU®β - agonists test kit is based on the competitive

    enzyme immunoassay for the detection of β - agonists in the

    urine, pork and other samples. The coupling antigen is pre-

    coated on the micro- well stripes. The β - agonists in the

    sample and the coupling antigens pre- coated on the micro-

    well stripes compete for the anti- β - agonists 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 β -

    agonists in the sample. This value is compared to the

    standard curve and the β - agonists residues is subsequently

    obtained.
