Product Introduction
The baker's yeast cultivated by high-density fermentation control technology is used as the raw material, and the powdery product obtained by concentration and spray drying using bio-oriented degradation and membrane filtration technology. This product is rich in nutritional components such as peptides, B vitamins, nucleotides, and has nutritional factors required to maintain cell growth and proliferation and promote cell protein expression. As a non-animal source medium raw material, it can realize animal serum in the medium Substitution of components. The endotoxin content of this product is less than 100EU/g.
Description
The product is a light yellow powder with good fluidity and uniform particles, which is easy to absorb moisture and is easily soluble in water.
√ The batch uniformity can be guaranteed;
√ Dry powder is easy to store and has good solubility, and it is also suitable for storage of high-concentration mother liquor;
√ Non-animal origin, no pathogenic factors, no GMO, no allergenic ingredients, low endotoxin content;
√ The components are clear and quantifiable, and the degree of protein hydrolysis is high;
√ Promote growth, stabilize proliferation, lower serum, and increase yield;
Application
As a supplement to protein, peptide, amino acid, carbohydrate, and micronutrient factors in the culture medium, it is suitable for vaccines, recombinant protein expression, insulin, interferon, monoclonal antibodies, and mammalian cells, insect cell culture.
