β-agonist ELISA test kit

β-agonists ELISA Test Kit Catalog No. LSY-10032 1. Principle The GreenSpring®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. 2. Technical specifications Sensitivity: 0.3 ppb Detection limit: Tissue ..............................................................................................
