Frederick Banting realized that this procedure would destroy the trypsin-secreting cells but not the insulin. 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 the number of universities that students can apply to, in 1991 the college introduced a new pre-university programme: the IB Diploma Programme. (The IB programme is recognised for admission into universities around the world.) To accommodate the growing programmes and students, a new 84-acre campus in Banting was constructed. On 1 July 1992, the new campus started operations under the name MRSM Banting with a 71 International Baccalaureate students from MRSM Cheras and 310 GCE A-Level students from MRSM Cheras and MRSM Seremban. In 1994, the name of the junior college was changed to Kolej MARA Banting (MARA College Banting)
