Extracted Carrier Protein

Conjugation of the target antigen with carrier proteins is also a development strategy for vaccines, such as conjugate vaccines. Binding with carrier proteins can enhance the immunogenicity of vaccines. Currently, approved carrier proteins on the market include diphtheria toxoid (DT), non-toxic mutant of diphtheria toxin CRM197, tetanus toxoid (TT), etc.

With a powerful process development platform, biosafety level BSL-1 and BSL-2 workshops, and a GMP quality system, Yaohai Bio-Pharma can provide customers with a one-stop solution from microbial strain development to GMP production of carrier proteins.

We deliver gram-to-kilogram-scale carrier proteins that meet quality standards, as well as GMP production records and testing reports to our customers.

Approved conjugated vaccines include the following carrier proteins (non-recombinant):
