Oxytetracyline ELISA Test Kit for honey safety

Oxytetracyline ELISA Test Kit
Catalog No. LSY-10044
1. Principle
This test kit is based on the competitive enzyme immunoassay for the detection of Oxytetracyline in the sample. The coupling antigens are pre-coated on the micro-well stripes. The Oxytetracyline in the sample and the coupling antigens pre-coated on the micro-well stripes compete for the anti- Oxytetracyline antibody. 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 Oxytetracyline in it. This value is compared to the standard curve and the Oxytetracyline concentration is subsequently obtained.
