The quinolones are a family of synthetic broad-spectrum antibiotics. The majority of quinolones belong to the subgroup of fluoroquinolones. Some of these fluoroquinolones are admitted as antibiotics especially for cattle, pigs, chicken, and fish/shrimp farming.
The Quinolones ELISA Kit produced by Meizheng significantly reduces both the testing cost and the operating difficulties.
Quinolones ELISA Kit is an indirect competitive enzyme-labeled immunoassay. The quinolones antigen is precoated on the wells. The precoated antigen compete the quinolones antibody (antibody solution) with quinolones in the sample, anti-quinolones antibody binds to the quinolones-HRP enzyme conjugate. Then pipette the substrate solutions to the wells to convert the color.
The color of unknown samples is compared to the color of the standards and the quinolones concentration of the samples is derived.
