Once the trypsin-secreting cells had died, insulin could be extracted from the islets of Langerhans. Banting discussed this approach with J. J. R. Macleod, Professor of Physiology at the University of Toronto. Macleod provided experimental facilities and the assistance of one of his students, Charles Best. Banting and Best, with the assistance of biochemist James Collip, began the production of insulin by this means. As the experiments proceeded, the required quantities could no longer be obtained by performing surgery on living dogs. In November 1921, Banting hit
Kolej MARA Banting to differentiate the college from the other MARA Junior Science Colleges and appropriately reflect the pre-university student body. The IB diploma depicts the name MARA College Banting in the transcript. The college has 94 lecturers with 41 support staff running day-to-day activities. Since May 2003, MARA College Banting has become a full-fledged 'IB World School'. Previously, MARA College Banting offered other pre-university programmes such as GCE A-Level and Matriculation but now only the IB programme. The college campus is in Bukit Changgang, Selangor, near Kuala Lumpur International Airport and Putrajaya. Students sit for their IB examination in May. Among the
