Monoclonal Antibodies Production

Monoclonal antibodies are highly uniform antibodies that are produced by a single B cell clone and are only directed against a specific epitope. It is usually prepared by hybridoma technology. Hybridoma antibody technology is based on cell fusion technology, fusion of sensitized B cells with the ability to secrete specific antibodies and myeloma cells with immortal proliferation capacity into B cell hybrids tumor. Now, CD BioSciences offers professional monoclonal antibodies production to meet the specific needs of different customers.

Overall solution

CD BioSciences provides you with professional monoclonal antibody preparation services, including antigen preparation, cell fusion screening, subcloning, monoclonal antibody preparation, etc.

CD BioSciences select the best immunization program according to the nature, quantity and purity of the antigen; and select the fusion cell by HAT selection medium, and perform ELISA positive screening and subcloning of the fusion cell; the positive monoclonal screened out, take the ascites, and use Protein The antibody is purified by A/G antibody purification column. The ELISA titer of the purified antibody is> 1: 128, 000, and the purity is> 90%.

CD BioSciences will customize a program suitable for your downstream applications and deliver high-quality monoclonal antibodies. The delivered monoclonal antibodies can be used for downstream experiments such as immunohistochemistry, ELISA, and in vitro diagnostic testing.

Protein antigen VS polypeptide antigen

Antigen epitopes recognized by antibodies include conformational epitopes and linear epitopes. Both epitopes can be recognized by antibodies prepared using proteins as antigens, and the resulting antibodies have a wide range of downstream applications. The antibodies prepared by using peptides can only recognize linear epitopes, and cannot guarantee that the obtained antibodies can recognize natural proteins; for downstream experiments (CO-IP, FACS, etc.) that need to recognize conformational epitopes of the antigen, antibodies prepared by using peptides are also very useful. It's hard to complete.
