Diabetes is a patient's pancreated islet cell that does not secrete insulin and has high blood sugar. The mortality rate of diabetic patients is second only to cancer and heart disease. About 60 million diabetes in the world.
Since 1921, the medical practice has always used insulin that can reduce blood sugar content in the human body to treat diabetes. However, insulin is mainly extracted from the pancreas of large livestock, such as cattle, pigs, can only produce 300 units or 30 ml of insulin, while a patient requires 40 units or 4 ml of daily. Insulin, obviously insulin production is far from satisfying. The advent of genetic engineering technology has provided a new way to solve this problem. The human insulin gene is a DNA molecule having a specific structure that directs insulin synthesis.
Scientists sent human insulin gene to E. coli, combined with the genetic substance of the insulin gene and E. coli. Human insulin gene offers Escherichia coli in Escherichia coli production of human insulin. With its reproduction, the insulin gene is also transmitted, and E. coli in the descendum can also produce insulin. This new genetic bacterium that belongs to artificial administration is called genetic engineering.
Gene Engineering Bacteria with human insulin gene is placed in a large fermentor, providing it to provide suitable conditions and nutrients, labor training, can breed a large number of people with a large number of people. E. coli is a "live factory" that produces insulin. In 1981, the human insulin gene products have been put into the market, solve the problem of insufficient insulin drugs.
The genetic engineering is to use the technology of genes to life science, benefiting humanity. It is mainly used to use different effects of amino acids.
