Abstract

The invention discloses a serum replacement for cell culture. The serum replacement is prepared from the following raw materials: manganese chloride, sodium selenite, ammonium molybdate, ferric citrate, choline bitartrate, vitamin D2, vitamin K2, vitamin K3, adenine, guanine hydrochloride, uracil, linoleic acid, cholesterol, insulin, hydrocortisone, dexamethasone, yeast hydrolysate, lactoprotein hydrolysate, casein hydrolysate and malt peptone. The serum replacement disclosed by the invention is added into a common basic culture medium and can be used for culturing cells, and can completely replace serum; the serum replacement does not contain IgG so that a monoclonal antibody produced antibody purification technology is greatly simplified; the cell culture is remarkably prolonged and thecells do not die; the production of protein and antibodies is facilitated; the cost can be greatly reduced and the production cost can be reduced.

Description

technical field [0001] The present invention relates to a serum substitute for culture medium, in particular to a serum substitute for cell culture. Background technique [0002] After decades of development, cell culture is now widely used in biology, medical technology, pharmaceuticals and other fields, forming a huge industry. Generally, bovine serum is often added to animal cell culture. Usually, animal cell culture is used for protein, antibody and vaccine production without using serum. 2) The quality difference between batches of products is reduced, and the repeatability and accuracy of the experiment are improved; 3) The composition of serum-free medium is clear, which avoids the influence of components on experimental research and is conducive to the development of cell metabolism. Basic research and the effect of specific components on cells; ④The serum-free medium is completely made of synthetic compounds, so the composition is determined, and the interference o...
