The invention discloses the preparation and application of a long-acting antibody gel preparation in the technical field of egg yolk antibody preparation, including purified antibody IGY and antibody preparations mainly composed of carbomer and chitosan quaternary ammonium salt. The preparation method of the antibody gel preparation is as follows: the purified antibody IGY is concentrated in a certain proportion to prepare carbomer and chitosan quaternary ammonium salt gel, and then the two are mixed according to the ratio of 10:1, and preservatives are added. After mixing, a suspension with a certain viscosity is formed, which has a certain slow-release effect, so that the antibody is injected into the body and released slowly to achieve a long-term effect, thereby reducing the number of times the antibody is used and prolonging the protection time. It is twice as long as the conventional antibody protection time, which is very convenient for users to use. |
