INTENDED USE

Hardy Diagnostics CRITERION™ Proteose Peptone No. 3 is frequently used as a nitrogen source in media formulations for culturing nutritionally fastidious microorganisms.

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

Proteose Peptone No. 3 is considered a versatile substrate because it can replace a meat infusion-peptone combination in infusion media. It is well suited for the growth of a large variety of organisms including streptococci, staphylococci, meningococci, pneumococci, gonococci, and other microorganisms requiring a highly nutritious substrate.

STORAGE AND SHELF LIFE

Store the sealed bottle containing culture medium at 2-30ºC. Dehydrated culture medium is very hygroscopic. Keep lid tightly sealed. Protect dehydrated culture media from moisture and light. The dehydrated culture media should be discarded if it is not free-flowing or if the color has changed from its original tan.

PRECAUTIONS

MATERIALS REQUIRED BUT NOT PROVIDED

Standard microbiological supplies and equipment such as autoclaves, incinerators, and incubators, etc., are not provided.

PHYSICAL APPEARANCE

CRITERION™ Proteose Peptone No. 3 powder should appear homogeneous, free-flowing, and tan in color.

The pH of a 2% solution of CRITERION™ Proteose Peptone No. 3 is approximately 7.0.
