Two-in-one colloidal gold reagent plate for detecting quinolones in aquatic products

Abstract

The invention discloses a two-in-one colloidal gold reagent plate for detecting quinolones in aquatic products. The reagent plate comprises a PVC detection plate, wherein the PVC detection plate is provided with a first detection groove and a second detection groove, one end of the first detection groove and one end of the second detection groove are respectively provided with a sample hole, and the other end of the first detection groove and the other end of the second detection groove are respectively provided with a sample hole; input plates corresponding to the first detection groove and the second detection groove are arranged on the PVC detection plate, the two input plates are clamped on the PVC detection plate, one ends of the two input plates correspond to the two sample holes, and the two sample holes are respectively communicated with the first detection groove and the second detection groove. The reagent plate is simple in structure, simple to operate, short in detection time, and capable of effectively adapting to the requirements of different environments, so a detection result can be well obtained in time, reaction sensitivity to a sample buffer solution is high, the detection result can be well obtained, the two detection grooves are used, and the reagent plate can specifically detect whether a certain quinolone medicine exists or not, and can also be used for repeated confirmation.

Description

technical field [0001] The invention belongs to the technical field of drug detection reagent plates, in particular to a two-in-one colloidal gold reagent plate for detecting quinolones in aquatic products. Background technique [0002] China is the world's largest aquaculture country and aquatic product trader. The output of aquaculture aquatic products accounts for about 70% of the world, and the problem of drug residues in aquatic products has always been the focus of attention. Quinolones, also known as pyroxic acid or pyridinic acid, are synthetic antibacterial drugs containing the basic structure of 4-quinolone, because of their wide antibacterial spectrum, strong antibacterial activity, strong tissue penetration, low price, It has no cross-resistance with other antibacterial drugs and has been widely used in aquaculture. However, unreasonable drug use can lead to the residue of quinolones and their metabolites in aquatic products, which will cause the imbalance of in...

Problems solved by technology

Microbiological methods are easy to operate, but the detection cycle is long and the sensitivity is low; instrumental methods, such as high performance liquid chromatography (HPLC), although very sensitive and accurate, are not suitable for on-site testing because of their high degree of instrumentation, complicated sample processing, and high detection costs. Rapid detection; ELISA also has shortcomings such as long detection time, high cost, and high requirements for testing personnel, which is not conducive to the promotion and use of grassroots units
