Abstract

The invention relates to a recombinant Wzt protein rabbit serum polyclonal antibody and a preparation method thereof, which relate to the field of antibody preparation, and fill the gap of applying recombinant Wzt protein for preparing the specific polyclonal antibody. The preparation method of the polyclonal antibody comprises the steps of after mixing and emulsifying the recombinant Wzt protein and an equivoluminal freund's complete adjuvant, carrying out multiple sites subcutaneous injection on the back parts of female rabbits; carrying out secondary immunizing: after one week, after mixing and emulsifying the recombinant Wzt protein and the equivoluminal freund's incomplete adjuvant, carrying out multiple sites subcutaneous injection on the back parts of the female rabbits; carrying out thrice immunizing and quartic immunizing every other week according to a secondary immunizing process; collecting venous blood of female domestic rabbit ears after immunizing each time, and detecting a rabbit serum antibody titer; at one week after quartic immunizing, collecting rabbit whole blood, centrifugally collecting a supernatant to obtain a rabbit serum, and obtaining the recombinant Wzt protein rabbit serum polyclonal antibody after purifying. The recombinant Wzt protein rabbit serum polyclonal antibody has favorable specificity, and can be used for detecting Brucella Wzt protein.

Description

technical field [0001] The invention relates to the technical field of antibody preparation, in particular to a recombinant Wzt protein rabbit serum polyclonal antibody and a preparation method thereof. Background technique [0002] Brucellosis (brucellosis, referred to as brucellosis) is caused by Brucella, mainly infecting ruminants and humans, and can also infect deer, dogs, etc. Brucellosis is infected in most parts of the world reports. [0003] Animals suffering from brucellosis can cause a series of problems such as abortion, reduced milk production and infertility in pregnant animals, which has a very large economic impact, especially in developing countries. The vast majority of Brucella can infect people and cause serious diseases, not only need to cooperate with the treatment of antibiotics, but also the treatment time is relatively long, and the sequelae left behind are usually relatively serious. The spread of brucellosis has seriously affected the development...
