Immunogenicity immunization

Envigo Bioproducts provides a unique Immunogenicity Immunization service in a variety of species, such as rats, mice, guinea pigs, and rabbits. We provide serum samples from a wide range of antigens, bacteria, viruses, lipids, nucleic acids and other proteins. Non-immunogenic haptens require conjugation with an epitope such as a protein or polysaccharide before they can illicit an immunologic response. Standard protocols are available for each species, or we can follow your specific protocol. All our procedures and production records are fully documented, allowing complete traceability.

Mouse antibody production (MAP) testing

If your Custom Antibody Production project must be free of mycoplasma or viral contamination, we recommend our mouse antibody production (MAP), rat antibody production (RAP) and hamster antibody production (HAP) testing programs. These tests will screen your cell lines against the adventitious viruses associated with your cell line’s origin. Testing is available by both PCR and serology.
