Abstract
Description
1. Technical field
[0001] The invention relates to recombinant human interferon alpha-2b and antiviral medicine. 2. Background technology
[0002] Interferon is a kind of protein induced by human cells when they are infected by viruses, which has anti-virus, anti-cell proliferation and immune regulation. According to antigen specificity and molecular structure, interferon can be divided into three types: α, β, γ interferon, among which α type interferon can be divided into three types.
[0003] The so-called natural interferon is induced and produced by human cells, some of which are leukocyte interferon derived from human blood. Due to the limited source of raw materials and difficult purification, the cost of preparing high-purity interferon is high and the yield is low. Moreover, there are potentially dangerous contaminations of hepatitis pathogens and HIV, which greatly limit the clinical application of interferon. In 1980, the United States successfully expressed the ...
