Because of the formulation, storage, disinfection, etc., even if some components are slightly different, it will not affect the balance between ions. MS solid medium can be used to induce callus, or for embryo, stem, shoot tip and anther culture, and its liquid medium can be used for cell suspension culture with significant success. The amount and proportion of inorganic nutrients in this medium are suitable to meet the nutritional and physiological needs of plant cells. Therefore, in general, it is not necessary to add an organic additional component such as an amino acid, a casein hydrolyzate, a yeast extract, or a coconut juice. The high content of nitrate, potassium and ammonium in the MS medium compared to the basic components of other media is a distinct feature. B5 medium. The main feature of B5 medium is that it contains lower ammonium because ammonium may inhibit the growth of many cultures. It has been found through experiments that some plant callus and suspension cultures grow better on MS medium than on B5 medium, while others are more suitable on B5 medium. N6 medium. N6 medium is especially suitable for anther and pollen culture of cereal plants, and is widely used at home and abroad. In tissue culture, often used is White (1963) medium, Nitsch (1951) medium, and the like. They are similar in basic composition. White medium is more suitable for tissue culture of woody plants because of the lower amount of inorganic salts. Drug research and development (1) New drug screening: such as the study of the efficacy of chemical synthetic drugs, screening and identification of active ingredients of traditional Chinese medicine. (2) Vaccine research and development: research and development of viral vaccines (hepatitis virus vaccine, AIDS vaccine, etc.), tumor vaccine (polypeptide vaccine), etc. (3) Research and development of genetic engineering drugs: such as interferon research and development, cell growth factor research and development. (4) Research and development of cell engineering drugs: research and development of biologically active peptides, research and development of bioactive components such as ginsenosides and paclitaxel. (5) Preparation of monoclonal antibodies: including monoclonal antibodies for diagnosis and monoclonal antibodies for treatment.
