Peptone From Gelatin
Catalog Number: AS-1007
CAS Number: 91079-43-5
Gelatin is extracted from collagen. Peptone from gelatin is enzymatic digestion of gelatin. Through this process, complex collagen molecules are broken down into smaller pieces that are ideal for bacterial growth.
In microbiology labs, peptone from gelatin is used as a source of complex nitrogen in culture media. For many non-fastidious bacteria, it supplies vital nutrients such free amino acids, nitrogen, and carbon sources. Peptone form gelatin also has low content of carbohydrates, cysteine, and tryptophan.
Shelf life and storage
Store Peptone from Gelatin between 10-30 °C in a ventilated and low humidity place and protected from light. Close the container tightly after use. Use before expiry date.
Note that peptone from gelatin is for R&D use only. DO NOT USE for drug, household, or any other uses.
