A Biotechnology Co., Ltd. Is a subsidiary of Tsinghua Science and Technology Park Incubator Co., Ltd., registered in Beijing Zhongguancun Science and Technology Park, a high-tech enterprise specializing in development, production, sales of cell culture, biological reagent products.
The company was established on February 20, 2004, the registered capital of 9 million yuan, introduced and developed mammalian cell culture medium production technology in 2001, and established a small-scale production workshop in accordance with GMP requirements. At the beginning of 2003, the market, product performance, quality reached the level of imported product, and received the recognition of many domestic vaccine production units, and the products were welcomed by users. In order to adapt to market demand, the company has established an annual production of 40 tons of powder cell culture medium in Changping Technology Park, with a 50-ton-liquid cell medium, and has been put into production. We will continue to produce more, higher standards. Cell cultured products to meet market needs.
Sodium chloride, is an inorganic ionic compound, a chemical NaCl, a colorless cube crystallization or a small crystalline powder, a salty. The appearance is a white crystal shape, its source is mainly sea water, and is the main component of salt. Soluble in water, glycerol, slightly soluble in ethanol (alcohol), liquid ammonia; insoluble in concentrated hydrochloric acid. In pure sodium chloride is toudized in the air. The stability is better, and the aqueous solution is neutralized, and the method of electrolytic saturated sodium chloride solution is generally used to produce hydrogen, chlorine and sodium alkali (sodium hydroxide) and other chemical products (generally referred to as chlor-alkali industries) can also be used for ore. Smelting (electrolytic melting sodium chloride crystals produces sodium sodium), medical use to configure physiological saline, and can be used in condiments.
Amino acid is an organic compound containing an alkaline amino group and an acidic carboxyl group, and the chemical formula is RCHNH2COOH. The hydrogen atom on the carbonate carbon atom is substituted with an amino group. Amino acid molecules contain both amino groups and carboxyl groups. Similar to the hydroxy acid, the amino acid can be divided into α-, β-, γ-, w -... amino acid according to different positions of the amino group, but the amino acid obtained after the protein is hydrolyzed is α-amino acid, And only twenty-two kinds include glycine, alanine, proline, leucine, isoleucine, methionine (methionine), proline, tryptophan, serine, tyrosine, Cysteine, phenylalanine, asparagine, valleyAxamine, threonine, aspartate, glutamic acid, lysine, arginine, histidine, selenium cysteine [1-2] and pyrroli lysine (found only in small bacteria ) They are basic units constituting the protein. Amino acids are basic substances that form the protein required for animal nutrition.
Glucose, organic compound, molecular formula C6H12O6. It is the most distributed and most important monosaccharide in nature, which is a polyhydrate. Pure glucose is a colorless crystal, sweet but sweet, is not as sucrose, soluble in water, slightly soluble in ethanol, insoluble in diethyl ether. The natural glucose solution is rotatably to the right, so it belongs to "Pretreatable". Glucose has an important role in biological fields, and is the energy source of living cells and metabolic intermediate products, ie, the main energy supply substance of the organism. Plants can produce glucose by photosynthesis. There is widely used in the confectionery manufacturing and pharmaceutical field.
