Oxytetracyline ELISA Test Kit for seafood

Oxytetracyline ELISA Test Kit

Catalog No. : LSY-10044B

1. Principle

This test kit is based on the indirect competitive enzyme immunoassay for the detection of Oxytetracyline in the fish and shrimp 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.
