Macleod saw the value of Banting and Best’s research and assigned the biochemist James Collip to purify (and increase the potency of) what we now know as insulin. The entire, hot, sticky summer of 1921, Banting and Best toiled in a tiny, smelly laboratory, gathering their data.īy fall, Banting and Best were still struggling to purify the hormone secreted by the cells of the pancreas - known as “islets of Langerhans” - when Macleod returned to Toronto.
Best, 21 years old at the time, won a coin flip, soon becoming the epitome of the curious medical student, and winning a role in medical history.īanting had no formal training in physiology, but had the great idea of ligating, or tying off, the pancreatic duct in order to isolate and collect the gland’s “internal secretion,” a yet-to-be-identified biological substance so essential to the body’s metabolism. Banting also got to choose one of two potential student assistants: Charles Best or Clark Noble. Macleod to let him use his laboratory, which came with research animals, while the senior scientist was away on summer vacation in Scotland. The story begins nearly 100 years ago, in 1921, when Ontario surgeon Frederick Banting convinced University of Toronto biochemistry professor J.J.R. On this day in 1899, one of the people responsible for that breakthrough, Charles H. Thankfully, the discovery of the pancreatic hormone paved the way to lifesaving treatments for people around the world.
