With the requirements of antibody quality control becoming increasingly more strict, research and production relying on animals may be reduced as more attention has shifted to in vitro techniques. Recombinant antibody production is completed in vitro, which overcomes the limitations of traditional antibody production. The whole production process is controllable and reliable with high repeatability and can ensure large quantity and long-term supply of target antibodies. Recombinant antibody production begins with constructing the antibody gene into the expression vector, and then uses the protein expression system to produce the recombinant antibody. Moreover, with the development of antibody engineering, computer algorithms, and genetic engineering methods, the antibody sequence can be modified and transformed and various types of antibodies can be produced. This includes full-length antibodies and various antibody fragments, such as scFv, Fab, etc.
