Product Description

EcoCRM™ is CRM 197 produced as a soluble intracellular protein in E. coli. CRM 197 is genetically detoxified diphtheria toxin. Specifically, it has a single amino acid substitution (glycine52 to glutamic acid), which causes the ADPribosyltransferase activity to be lost. CRM 197 is widely used as the carrier protein for conjugate vaccines. EcoCRM™ is expressed as a recombinant protein in Escherichia coli. ;

The theoretical molecular weight of the protein is 58.4 kDa.;
