A specialised peptone prepared from a mixture of peptones. This product contains proteoses as defined in the United States Pharmacopoeia9. This has been achieved by carefully controlling manufacturing conditions to achieve a product rich in the higher molecular weight peptides, (e.g. 4000 plus).
Proteose Peptone is especially suitable in media for Corynebacterium diphtheriae toxin, including that for the Elek reaction for the recognition of toxigenic strains, as well as in the media for the production of toxins from staphylococci, clostridia and salmonellae. Media incorporating this peptone are suitable for the cultivation of different bacteria with a wide range of nutritional requirements, e.g. Neisseria, Staphylococcus, Haemophilus, Salmonella, Pasteurella, Corynebacterium and Histoplasma species.
It is the peptone used to manufacture diptheria toxoid, pertussis vaccine and measles vaccine.
