Embodiment Construction

[0008] In one embodiment, the present invention provides a method for producing a therapeutic canine parvovirus monoclonal antibody, comprising the steps of:

[0009] (1) Inoculate the hybridoma cells secreting anti-canine parvovirus monoclonal antibody into the culture medium in the bioreactor;

[0010] (2) cultivating hybridoma cells in a bioreactor;

[0011] (3) Harvest the anti-canine parvovirus monoclonal antibody produced by the hybridoma cells.

[0012] In the present invention, "bioreactor" refers to a bioreaction device that provides a good closed environment for culturing growing and non-immobilized cells, and is usually also called a cell fermenter. A variety of bioreactors may be suitable for use in the present invention, including, for example, stirred bioreactors, airlift bioreactors, hollow fiber bioreactors, and fluidized bed bioreactors, among others.

[0013] There are three main types of bioreactor cell culture: batch, fed-batch and perfusion. In simple b...

Abstract

The invention discloses a method for producing a curative canine parvovirus virus monoclonal antibody by using a bioreactor.

Description

technical field [0001] The invention relates to the technical field of monoclonal antibody production, in particular to a method for producing therapeutic canine parvovirus monoclonal antibody with a bioreactor. Background technique [0002] In 1975, Koehler and Milstein (Nature Vol.256, pp 495-497) used hybridoma technology to prepare the world's first mouse monoclonal antibody, which opened up a new field for biotechnology. With the development of biotechnology, monoclonal antibody technology has also made great progress. Today, monoclonal antibodies have been widely used in various fields of biomedicine (including human and veterinary medicine), especially in the field of basic research and clinical application of the prevention and treatment of viral infections, and are increasingly playing an extremely important role. [0003] Canine parvovirus (Canine Parvovirus, CPV) infection is an acute infectious disease in dogs. In 1978, Kelly in Australia and Thomson in Canada ...
