Disposable, integrated and large-scale are the development trend of cell gene therapy production equipment and technology.

After the cells are inoculated or subcultured, the experimenter should make routine examination of the cells every day or at most 1 ~ 2 days. Observe the morphology and growth of cells, as well as the pH change of culture, whether there is pollution, etc. According to the dynamic changes of cells, do fluid replacement or passage treatment. If abnormal conditions are found, take measures in time.

Vaccine is an automatic immune agent for the prevention of infectious diseases, which is made of pathogenic microorganisms (such as bacteria, viruses, etc.) and their metabolites through artificial virus reduction, inactivation or genetic engineering. According to the different types of infectious disease pathogens it prevents, it can be roughly divided into bacterial vaccines and viral vaccines. Many viral vaccines used in the population now need to be prepared through the process of virus culture, purification, concentration, inactivation or lysis. Because virosomes are a kind of parasitic microorganisms specialized in host cells, their reproduction needs to be carried out in their specific host cells. Therefore, the cultivation of viruses in the production of viral vaccines requires the cultivation of animal cells in which the virosomes can reproduce first.

When it comes to vaccines, there are many kinds, including: virus vaccines, protein based vaccines, viral vector vaccines, nucleic acid vaccines - what kind of vaccines are they? What are the advantages and disadvantages?

Experts believe that automation and informatization are the only way to ensure the quality of drugs. If this is not well understood in the industry, it is relatively difficult to promote this aspect. In terms of automation, the production process of the pharmaceutical industry can not simply apply automation, which can change some problems, especially in pharmaceutical equipment.
