A large number of laboratory and clinical research data show that the immune response of HPV host plays a very important role in controlling HPV infection and related diseases. Low immune status to HPV is prevalent in patients with HPV precancerous lesions and cervical cancer. HPV preventive vaccine mainly uses synthetic L1 late protein virus like particles with natural spatial structure as the target antigen to induce the body to produce high titer serum neutralizing antibodies to neutralize the virus and assist tumor specific killing T lymphocytes to eliminate virus infection.

Characteristics of biotechnology drugs:

What is the effect of adding double antibodies to cell culture

The main functions of the preparation area are cleaning, disinfection and preparation; The preparation area is mainly used for the preparation of culture media and reagents; The storage area is used for cell bank and goods storage; The sterile area is the place where the laboratory personnel change clothes, buffer and cultivate. The process of cell culture can be divided into four parts according to their functions: cell culture, storage, preparation and sterilization.

A cell culture tube is a test tube for culturing cells. It can be divided into disposable culture tubes and reusable tubes, but most of them are disposable. According to the material classification, there are mainly polyethylene, polypropylene, polystyrene and so on. Polyethylene and polypropylene tubes have good chemical resistance and high mechanical strength, which are suitable for serological research of low protein adsorption; Polystyrene is suitable for a wide range of applications.

In recent decades, due to the rapid development of the biological products industry, the traditional method of obtaining biological products from animal tissues through biochemical technology has been far from meeting the market demand. It has become a very common technology to express specific proteins, monoclonal antibodies, interferons and viral vaccine products through large-scale cultivation of animal cells in vitro.
