EcoCRM™ Diptheria Toxin CRM197 Mutant Vaccine Carrier Protein EcoCRM™ is CRM197 produced as a soluble intracellular protein in E. coli. CRM197 is a genetically detoxified diphtheria toxin. Specifically, it has a single amino acid substitution (glycine52 to glutamic acid), which causes the ADP-ribosyltransferase activity to be lost. CRM197 is widely used as the carrier protein for conjugate vaccines. EcoCRM™ is expressed as a recombinant protein in Escherichia coli and purified by HPLC.
  • Formulation: Supplied in PBS, pH 7.6 and 10% glycerol
