INTENDED USE

Hardy Diagnostics CRITERION™ Pancreatic Digest of Casein is a general purpose growth peptone used as a nitrogen source in culture media formulated for isolating and cultivating fastidious and nonfastidious bacteria and fungi and some protozoa.

This is a raw material intended to be used in the making of prepared media products, which will require further processing, additional ingredients, or supplements.

SUMMARY

Casein Peptone (Pancreatic Digest of Casein) is recommended for use in culture media for detecting bacteria of sanitary significance in dairy products and treated and untreated waters, for sterility testing and for assaying antimicrobics. Casein Peptone can be used for indole testing because of its high tryptophan content. It is biologically free of carbohydrates and is recommended for fermentation studies. Nitrate reduction can also be determined using this peptone.

STORAGE AND SHELF LIFE

The dehydrated culture media should be discarded if it is not free-flowing or if the color has changed from its original light tan.
