Antibody Production by In Vitro Immunization

With years of extensive experience, Creative Biolabs now is proud to offer the in vitro immunization service for the customize antibodies production. As one of the most efficient immunization strategies, in vitro immunization plays an important role in the monoclonal antibody production.

Introduction of In Vitro Immunization

In the field of biological research, obtaining a high-affinity and high-selectivity antibody is essential for meeting the requirements in diagnostics and therapeutics. As one of the highest efficiency methods, in vitro immunization has taken a series of advantages to establishing the antibody with the desired selectivity and affinity against varies of antigens compared with the conventional immunization method. Through the in vitro immunization, the immune cells will be isolated from the naïve animals and stimulated with the antigen in vitro, this will then result in the induction of B-cells which have the ability to produce the antigen-specific antibodies for the further screening.

In Vitro Immunization-based Human Antibody Production

Creative Biolabs has developed a high-efficiency protocol to induce specific antigen immune response in human peripheral blood mononuclear cells (PBMCs) for the production of human mAbs on the basis of in vitro immunization. The PBMCs which directly isolated from human blood cannot show the sensitization to antigens because of the suppressed function from the immunosuppressive cells such as monocytes and NK cells. However, after the treatment with L-leucyl-L-leucine methyl ester (LLME), the PBMCs are able to initiate the immune response against any antigens as the immunosuppressive cells have been removed. After the in vitro immunization, the antigen-specific antibody genes can be isolated from the library with the help of varies display methods. Combined with our Native™ Human Antibody Discovery Service, Creative Biolabs is able to discovery antigen specific human antibodies with naïve pair heavy- and light-chain.
