Problems solved by technology

[0005] Most of the existing detection methods for kanamycin, erythromycin and lincomycin are instrumental methods, such as HPLC, HPLC-MS / MS, GC-MS / MS, etc. These instrumental methods have high sensitivity and can provide quantitative and confirmation analysis, but the pre-treatment is complex, requires expensive instruments, and has professional requirements for operators, so it is not suitable for basic-level detection and analysis
In addition, in the actual breeding process, animals may use a variety of antibiotics at the same time, and the existing detection technology can only detect one or a type of drugs. products with residues

Abstract

The invention discloses a kanamycin, erythrocin and lincomycin three-in-one gold-labeled micro-hole strip. A kit comprises a sample plate at least provided with one sample groove and at least one test strip; a colloidal gold-labeled object of a kanamycin specific antibody, a colloidal gold-labeled object of an erythrocin specific antibody and a colloidal gold-labeled object of a lincomycin specific antibody are attached to the bottom of each sample groove; the test strip comprises a bottom plate (1), a reaction film (2), a sample absorbent pad (3) and an absorbent pad (4), wherein the sample absorbent pad, the reaction film and the absorbent pad are sequentially attached to the bottom plate; a line T3, a line T2, a line T1 and a line C are sequentially arranged on the reaction film from beginning to tail end, and the line T3, the line T2 and the line T1 are coated with a lincomycin-carrier protein coupling, an erythrocin-carrier protein coupling and a kanamycin-carrier protein coupling respectively; the C line is coated with an antiantibody. The kit has the wide market prospect.

Description

technical field [0001] The invention belongs to the field of food safety detection, in particular to a method for simultaneously detecting the contents of kanamycin, erythromycin and lincomycin in animal-derived foods (such as milk, etc.) Mycin three-in-one gold standard microporous test strip. Background technique [0002] Kanamycin (Kanamycin) belongs to aminoglycoside antibiotics, has good antibacterial effect on various Gram-negative bacteria and Gram-positive bacteria, and is suitable for treating bacillary dysentery or other bacterial intestinal infections. One of the veterinary drugs commonly used in my country's animal husbandry and aquaculture, it is also often added to feed to promote the growth and development of animals. Although kanamycin has good pharmacological effects, its ototoxicity and nephrotoxicity are also relatively serious, so its residues in animal products have increasingly attracted people's attention. In order to strictly control the residues of ...
