*the advantage is that it is the only viable source of clinical quantities of human insulin. Before it's FDA approval for Genetech patients would inject animal insulin purified from animal tissue. Disadvantages? From the frame of mind that is the ONLY source of externally provided human insulin it is hard to attribute disadvantages.
Can be mass produced since it does not rely on animal tissue as raw material for insulin extraction
There is significant consistancy between batches
the advantages and disadvantages of using artificial insulin
are...
where am i ?
whats going on?
who are you?
Human Insulin Human Growth Hormone (HGH)
Type I diabetes that cannot be successfully treated with animal insulin.
Apart from idealogical concerns there shouldn't be any. Genetically engineered insulin is much, much safer than extracting insulin from pig's panreas as they did before they isolated the human insulin gene.

Insulin
One way insulin can be produced is by injecting genetically engineered bacteria into your bloodstream. The insulin will multiply and each one will produce insulin. This is only helpful in fighting on kind of diabetes.
C)Pigs and cows
Genetically engineered insulin may have fewer side effects than the insulin previously extracted from the pancreases of other animals. This is because genetic engineering inserts human genes such as the gene for insulin production into the DNA of bacteria. As a result, the bacteria that produces human insulin, when used by diabetics, should produce fewer side effects.
Advantages * Cheaper to be made then by normal methods * the E.coli bacteria are friendly to the body * bacteria can be placed in yoghurt- 1-3 yoghurt's a day should be all you would need * bacteria can produce exact amount of insulin needed in response to the host's needs * no allergy problems - using pig insulin caused problems for people allergic to pigs Disadvantages * is still being tested with mice * yoghurt would need to be eaten regularly to replace bacteria
Insulin can come from a number of sources. It is sometimes extracted from the pancreas of a pig, but it can also be made by genetically engineered bacteria. So for a particular batch of insulin, you would have to find out how it was made.
E. coli that contains the gene for human insulin is genetically engineered, transgenic, and a GMO. Bacteria have been engineered to produce chymotrypsin, make human insulin, produce enzymes that increase shelf life of bread, and to produce enzymes that improve the taste and clarity of beer.
True in the 'manufacture' of Human Insulin - 'Humulin" genetically engineered bacteria are used to produce drugs and other chemicals that benefit humans.
