Problems solved by technology

[0002] Doxycycline is one of the important members of tetracycline antibiotics. It is widely used clinically in animal husbandry and veterinary. The accumulation of residues in feeding tissues not only leads to the emergence of drug-resistant bacteria, but also seriously affects the export of animal husbandry products in my country, causing major economic losses, and also brings great harm to the physical and mental health of consumers. In addition, breeders also There are medication regulations that do not comply with the drug dosage, drug administration site, and drug animal species, as well as the phenomenon of repeated use of several drugs with different trade names but the same ingredients. Therefore, it is necessary to strengthen the monitoring of veterinary drug residues in food of animal origin

Abstract

The invention discloses a doxycycline broad-spectrum monoclonal antibody and a preparation technology. The doxycycline broad-spectrum monoclonal antibody is prepared from the following raw materials in parts by weight: 40-52 parts of doxycycline, 4-20 parts of tetracycline, 2-6 parts of minocyclin, 2-4 parts of metacycline, 3-5 parts of bovine serum albumin, 5-8 parts of a Freund's complete adjuvant, 1-2 parts of Freund's incomplete adjuvant, 2-3 parts of HRP-Goat anti Mouse IgG, 3-6 parts of ammonium sulphate, 9-10 parts of disodium hydrogen phosphate, 16-20 parts of potassium dihydrogen phosphate, 12-16 parts of citric acid, 8-12 parts of ammonium dihydrogen phosphate, 9-15 parts of anhydrous ethanol, 1-3 parts of isobutyl chlorocarbonate, 2-4 parts of a coating buffered solution, 5-7 parts of confining liquid, 3-4 parts of a washing buffered solution, 6-10 parts of substrates and 20-25 parts of cell culture fluid, wherein the doxycycline and 4-Aminophenylacetic acid are used as main raw materials, and a diazo method is used for preparing the doxycycline broad-spectrum monoclonal antibody having antisera specificity. The doxycycline broad-spectrum monoclonal antibody has excellent biological properties, and is good in antisera titer and rejection capability.

Description

technical field [0001] The invention relates to the field of doxycycline antibody preparation technology, in particular to a doxycycline broad-spectrum monoclonal antibody and a preparation technology. Background technique [0002] Doxycycline is one of the important members of tetracycline antibiotics. It is widely used clinically in animal husbandry and veterinary. The accumulation of residues in feeding tissues not only leads to the emergence of drug-resistant bacteria, but also seriously affects the export of animal husbandry products in my country, causing major economic losses, and also brings great harm to the physical and mental health of consumers. In addition, breeders also There are medication regulations that do not comply with the dosage, administration site, and species of animals used, as well as the phenomenon of repeated use of several drugs with different trade names but the same ingredients. Therefore, it is necessary to strengthen the monitoring of veterina...
