Company Profile

1. Principle

This test kit is based on the competitive enzyme immunoassay for the detection of zilpaterol in the pork , liver, urine. The coupling antigen is pre-coated on the micro-well stripes. The zilpaterol in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti-zilpaterol 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 zilpaterol in it. This value is compared to the standard curve and thezilpaterol residues is subsequently obtained.
