​β-agonists ELISA Test Kit For Feed

  • Sep 02, 2026   Anon

β-agonists ELISA Test Kit                         

Catalog No. LSY-10036

1. Principle

The GreenSpring®β-agonists test kit is based on the indirect competitive enzyme immunoassay for the detection of β-agonists in the sample. 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.
