1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of Ractopamine in the pork. The conjugate antigen is pre-coated on the micro-well stripes. The Ractopamine in the testing sample competes with the conjugate antigens pre-coated on the micro-well stripes, to interact with the antibodies against Ractopamine. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density ( OD) value of the testing sample has a negative correlation with the content of Ractopamine in it. This value is compared to the standard curve and the content of the corresponding Ractopamine is subsequently obtained.
