Abstract

The invention discloses a low-serum cell culture medium with universal adaptability and a preparation method thereof, and belongs to the technical field of biochemistry, the preparation method comprises the following steps: (1), compounding solvent: dissolving trace materials into 940 to 1060 parts by mass of ultrapure water, compounding to be a solvent; (2), drying: mixing the solvent obtained in the step (1) with 1000 to 4500 parts by mass of D-glucose and drying; (3), ball milling: taking other raw materials and mixing uniformly with dried mixed materials in the step (2), then performing ball-milling, sieving through a 100-mesh screen, taking the sieved parts to prepare the culture medium. The culture medium has universal adaptability, can be applied to various cell lines such as VERO, BHK-21, A549, ST, PK-15; transition is not needed when cells is transferred from a high-serum culture medium to the low-serum cell culture medium provided by the invention during a culture process, the cells can adapt quickly, and the operation is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and in particular relates to a low-serum cell culture medium with wide adaptability and a preparation method thereof. Background technique [0002] Cell culture has been widely used in basic and applied research in biology and medicine, and has also achieved large-scale production and application in the biopharmaceutical industry. It is one of the most important basic sciences. [0003] With the rapid development of biomedicine, the demand for vaccines, monoclonal antibodies and other biomedical products in the market continues to increase, and more and more biopharmaceutical companies have emerged as the times require. Traditional cell culture has a great demand for animal serum, and due to changes in the animal husbandry industry, the price of animal serum continues to rise, which increases the economic burden on enterprises. [0004] The low-serum cell culture medium not only contains a ...
