See the offer sheet for a complete list of quality control strains and specifications for their use.
All quality control strains are supplied as lyophilized cultures and a selected group is also supplied on gelatin discs.
Cultures on gelatin discs
Gelatin discs replace the storage of cultures on agar. This reduces the risk of contamination and loss of viability during subculturing. They give standard results of controlled tests. They are supplied in screw cap vials that allow for easy, aseptic and repeatable culture collection. Each vial contains 20 discs. The expiration period is 1-2 years. The CCM reserves the right to use up to half of the total expiration date. Discs should be protected from light and moisture and stored in a refrigerator at 2 to 8 °C. Gelatin discs are shipped under common transport conditions.
