Descripción

General description

Bacteriological Meat Peptone is a high clarity and stability pancreatic hydrolysate of animal tissues designed for culture media applications. It is a growth-promoting nitrogenous nutrient (peptides and amino acids) with a neutral pH. It has a high sulfur compound content which makes it suitable for the detection of microbes (Clostridia spp., Salmonella spp.) producing hydrogen sulfide. It is also used in animal cell culture and microbiology culture media.

Application

Bacteriological meat peptone is a rich source of organic nitrogen and therefore used in a variety of media preparations to cultivate yeasts and molds, Enterobacteria and Staphylococci. It can also be used for the commercial production of vaccines, steroids, antibiotics, enzymes and other products. In recent times it has also been used as a medium additive for the production of recombinant therapeutic proteins

Biochem/physiol Actions

Peptone supplementation in media helps to increase cell number, specific monoclonal antibody production and also the period of long term culture.
