Really? So Einstein what are we going to do with all the GMO's used in our medical field that have saved countless lives.

Humulin is the brand name for a group of biosynthetic human insulin products, developed by Arthur Riggs, working with Genentech in 1978 (Generic names regular insulin, insulin isophane and the Lente series consisting of Lente (known generically as insulin zinc suspension) is actually a mixture of Ultralente and Semilente) and later acquired by Eli Lilly and Company, the company who arguably facilitated the product's approval with the U.S. Food and Drug Administration. The Lente series was discontinued by Lilly in 2005. Prior to the development of synthesized human insulin, patients were dependent on animal insulin which was more costly, less accessible, and caused infections in some patients.

Humulin is synthesized in a laboratory strain of Escherichia coli bacteria which has been genetically altered with recombinant DNA to produce biosynthetic human insulin. Humulin R consists of zinc-insulin crystals dissolved in a clear fluid. The synthesized insulin is then combined with other compounds or types of insulin which affect its shelf life and absorption. For example, Humulin N is combined with protamine to extend the time-activity profile of Humulin R for an extended period.
