Beta-agonist ELISA test kit Catalogue No.: LSY-10036 |
Brief b-agonists are growth-promoting agents used in meat producing livestock. Clenbuterol and salbutamol are often mentioned in the illegal use of b-agonists as feed additives. Misuse of these can cause drastic side effects, such as cramps, tremors, hypertension, dizziness and nausea. The b-Agonist EIA (enzyme immunoassay) kit is a direct competitive immunoassay for the detection of b-agonists in various matrices. We can get the assay results in 45 min with the kit. |
Principle The GreenSpring®β-agonists test kit is based on the competitive enzyme immunoassay for the detection of β-agonists in the urine, tissue and other samples.The coupling antigen is pre-coated on the micro-well stripes. The β-agonistsin the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-β-agonistsantibodies. 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-agonistsin the sample. This value is compared to the standard curve and the β-agonists residues is subsequently obtained. |
