Basic Info of Peptone

What is Peptone?

Proteose peptone is a nutrient rich peptone. Peptone (protein hydrolysate) is widely used as a source of protein in culture medium. They are soluble mixtures of polypeptides and also amino acids formed by hydrolysis of pet and plant healthy proteins.

Peptone is a water-soluble protein hydrolysate, which contains peptides, amino acids, inorganic salts and other compounds, such as lipids, vitamins and sugars. In stable and transient expression systems, plant derived peptone can improve cell growth and increase specific productivity and volume productivity.

Adding peptone to the culture medium can help to increase the number of cells, the production of specific monoclonal antibodies and the time of long-term culture.

Peptone Uses

  1. Peptone is widely used as a supplement to serum-free medium. The growth promoting activity of peptone may play a dual role in batch culture, and it may promote the rapid growth of cells on the first day of culture.
  2. Peptone, mycology, has been used as a component in phospholipase agar plate for phospholipase determination.
  3. Peptone may also lead to early consumption of important nutrients and associated release of toxic metabolites, faster decline of culture activity, apoptosis and release of proteases that may degrade products.
  4. This product is obtained by partial digestion and hydrolysis of pepsin. It can be used for routine culture of a variety of microorganisms. USP specifies that this product is used for sterility test, and is recommended for Streptococcus cultivation and hydrogen sulfide producing microorganism detection.
  5. Highly nutritious peptone is used for the production of bacterial toxins in the culture medium and for the culture of bacteria with high nutritional needs, such as Corynebacterium, Haemophilus, Neisseria, Pasteurella, Salmonella and Staphylococcus. The product is rich in high molecular weight peptides.
