Carrier Proteins

Carrier proteins are used to convert polysaccharides from T-cell independent antigens, into T-cell dependent antigens by linking the two together.  They are also used to improve the immunogenicity of oligosaccharides, peptides and proteins.

CRM197 Carrier Protein

CRM197, a genetically detoxified diphtheria toxin, is widely used as a carrier protein in conjugate vaccines, including effective conjugate vaccines against Streptococcus pneumoniae, Haemophilus influenzae b and Neisseria meningitidis. Fina BioSolutions has developed a highly efficient E. coli expression system for CRM197. We express soluble, properly folded CRM197 in the cytoplasm of E.coli. High expression levels and a simple purification scheme allow us to produce CRM197 at low cost and price it accordingly.

Fina Biosolutions is pleased to offer EcoCRM®, economical CRM197 from E. coli, to the research and vaccine manufacturing community. Research Grade EcoCRM® is available now. cGMP EcoCRM® is now available.
