At Primrose Bio, we leverage CRM197 carrier protein to enhance conjugate vaccines, improving immune responses and contributing to innovative, effective solutions for global health.
CRM197 is a non-toxic mutant of diphtheria toxin having a single amino acid substitution of glycine with glutamic acid. CRM197 is a well-defined protein and functions as a carrier for polysaccharides and haptens making them more immunogenic. CRM197 is utilized as a carrier protein in a number...
Fina Biosolutions, a leading expert in conjugate vaccines, helps vaccine developers and manufacturers learn how to make affordable conjugate vaccines. Fina Biosolutions offers a variety of bioconjugation and protein services, including the carrier protei
Conclusion The structures of three batches of prepared CMR197 protein were basically consistent with that ofstandard CMR197 protein,which laid a foundation of development of polysaccharide conjugate vaccine using CRM197 asa carrier.Key words: Diphtheria toxin;Avirulent mutant;CRM197 protein;Structure ...
Conjugate vaccines using diphtheria toxoid variant (CRM(197)), diphtheria toxoid and tetanus toxoid (TT) as carrier protein may induce immune interactions (interference or impairment as measured by lo... Antitumor effects of CRM197, a specific inhibitor of HB-EGF, in T-cell acute lymphoblastic ...
The protein nonetheless retains the same inflammatory and immunostimulant properties as thediphtheria toxin, and it is widely used as a safe carrier in conjugatedvaccines. A new and alternative procedure for the production of full-length CRM197 in Corynebacterium diphtheriae was proposed. The gene of...
all potential carrier proteins and vaccine adjuvants. Recently List Labs has produced genetically altered pertussis toxin which retains some toxin activity and may be used as a carrier protein/vaccine adjuvant. List Labs vaccine carrier proteins and adjuvants are provided for research use only; howeve...
In this study, we designed a novel polypeptides vaccine conjugated to a CRM197 carrier protein, encoding 15 CD8+ T-cell epitopes, five CD4+ T-cell epitopes, and four B-cell epitopes from gB287–320 and pp150311–325 of HCMV to induce T-cell immune responses. To evaluate the ...
