Abstract

The invention relates to a test strip for rapidly detecting trace sulfachlorpyridazine and a preparation method thereof. According to the test strip, the bottom layer is a support layer, the middle layer is an adsorption layer, and a protection layer is fixed on the adsorption layer; the adsorption layer sequentially comprises an adsorption fibre layer, a gold-labelled antibody fibre layer, a cellulose membrane layer and a water-absorbing material layer from a test end; a detection imprint printed by carrier protein solution coupled with sulfachlorpyridazine, and a control imprint printed by goat anti-mouse IgG antibody solution or rabbit anti-mouse IgG antibody solution or goat anti-rabbit IgG antibody solution are formed on the cellulose membrane layer; a gold-labelled antibody is a colloidal gold-labelled sulfachlorpyridazine antibody. The test strip disclosed by the invention is strong in specificity, high in sensitivity, simple and convenient, intuitive, accurate, wide in application range, low in cost, simple and convenient to operate, capable of meeting the needs of personnel in different levels, wide in market prospect, and easy to popularize and apply.

Description

technical field

[0001] The invention belongs to the field of immunochemical detection of veterinary drug residues, in particular to an immunocolloidal gold test strip for rapidly detecting trace amounts of sulfachloropyridazine and a preparation method thereof. technical background

[0002] Sulfachloropyridazine (sulfachloropyridazine, SPDZ) molecular formula C 10 h 9 ClN 4 o 2 S, with a molecular weight of 284.72, is a kind of synthetic antibacterial drug that inhibits nucleic acid synthesis. It belongs to a broad-spectrum antibacterial drug. It has the characteristics of low toxicity and easy absorption after oral administration. Antibacterial effect. Due to the low price and effective antibacterial effect of sulfa drugs, they are widely used in animal husbandry as preventive and therapeutic drugs. However, the unreasonable use or even abuse of sulfachloropyridazine will cause the emergence of drug-resistant strains on the one hand, leading to the pollution of animal ...
