Abstract

The invention provides preparation and application of a tetracycline sample pretreatment kit based on immunomagnetic beads. The kit mainly consists of several parts including a sample cabin, a reagentcabin, a cleaning cabin, an elution cabin and the like. The operation method has the advantages that the efficiency and the speed are high; the operation is simple; large-scale instruments and specially trained professional operation personnel are not needed; the sample does not need special pretreatment, and can be widely applied to tetracycline enrichment and separation in products of animal tissues, water products, meat products and the like; for tetracycline samples with a value lower than the detection limit, through the enriching effects of immunomagnetic beads and the sufficient diffusion of the immunomagnetic beads in the liquid, the combination surface area is expanded; the reaction is thorough, so that the detection limit is changed; the detection sensitivity is improved; the inspection missing phenomenon is avoided.

Description

Technical field [0001] The invention belongs to the field of food biological detection and analysis, and specifically relates to a tetracycline sample pretreatment kit based on immunomagnetic beads. Background technique [0002] Tetracyclines are named after the similar molecular structure of the hydrogenated tetraphenyl ring. They are broad-spectrum antibiotics, and their use accounts for 57% of the total antibiotic use in my country. Because of its broad-spectrum and high-efficiency sterilization effect and low price, it can be used to prevent and treat fish diseases in the process of aquaculture. It can be used in the dairy industry to increase milk production in dairy cows. It can also prevent and treat livestock diseases. It can also be used as a feed additive to promote the growth of poultry and livestock, so it has a wide range of applications. However, excessive use of tetracycline antibiotics will inevitably leave mothers, metabolites and other related antibiotics in th...
