This test kit is based on the indirect competitive enzyme immunoassay for the detection of Neomycin in the sample.Thecoupling antigenis pre-coated on the micro-well stripes. TheNeomycin residues in the sampleand thecoupling antigen pre-coated on the micro-well stripes compete for the anti-Neomycinantibody. 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 theNeomycin in it. This value is compared to the standard curve and theNeomycin concentration issubsequently obtained.

4. Materials required but not provided
1) Equipment:microplate reader, printer,homogenizer,vortex, centrifuge, measuring pipets, andbalance( asensibility reciprocalof0.01g), incubator.
2) Micropipette: single-channel 20-200µL, 100-1000µL, andmulti-channel30~300µL.
3) Reagents: Trichloroacetic acid(TCA), NaOH, HCl, deionized water.
Thefollowing pointsmust be dealt with beforethe pre-treatment ofany kind ofsample:
1)Only thedisposable tips can be used for the experiments and the tips must be changed when used forabsorbingdifferent reagents;
2)Before the experiment, eachexperimentalequipment must be checked to beclean and should be re-cleaned ifnecessary,in order to avoid thecontamination thatinterfereswith the experimental results.
