CRM197 is a genetically detoxified diphtheria toxin with glutamic acid substituted for glycine at position 52. Fina Biosolutions (FinaBio) offers protein-A purified antibodies for the detection of CRM197 and diphtheria toxin in ELISA and Western blot applications. Rabbit polyclonal and mouse monoclonal antibodies are available, in both unlabeled and biotinylated forms. EcoCRM®, FinaBio’s E. coli expressed CRM197, was used as the immunogen for the antibody production, however, the antibodies should recognize Corynebacterium diphtheria toxin and toxoid.
