Peptone ex gelatin, pancreatic digest, for microbiology, 500 g, plastic

Peptone ex gelatin, pancreatic digest is a microbiological culture ingredient obtained by pancreatic digestion of gelatin. It is used in microbiology as a nutrient peptone component for media preparation supporting growth of a wide range of microorganisms in research, quality control and teaching laboratories. Identified by CAS number 91079-43-5 and EG number 293-431-0, the material is supplied for standard microbiological applications where a gelatin-derived pancreatic digest is specified. The pack contains 500 g in plastic, a practical quantity for media kitchens and routine culture-media production. This peptone from manufacturer Carl ROTH can be incorporated into broths and solid media according to established formulations that call for peptone from gelatin. Its defined origin as a pancreatic digest helps laboratories select the appropriate nitrogen and peptide source when composing selective or general-purpose media. The 500 g unit supports both small-batch preparation and ongoing media manufacture without requiring oversized bulk containers.
