1. Principle

The BIOKAU^? Neomycin ELISA test kit is based on the competitive enzyme immunoassay. The coupling antigen is pre-coated on the micro-well stripes. The Neomycin residues in the sample and the coupling antigen pre-coated on the micro-well stripes compete for the anti-Neomycin 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 Neomycin in it. This value is compared to the standard curve and the Neomycin concentration is subsequently obtained.
