Coomassie brilliant blue G-250 acts as a potential chemical chaperone to stabilize therapeutic insulin

Abstract

Our studies show Coomassie Brilliant Blue G-250 as a promising chemical chaperone that stabilises the α-helical native human insulin conformers, disrupting their aggregation. Furthermore, it also increases the insulin secretion. This multipolar effect coupled with its non-toxic nature could be useful for developing highly bioactive, targeted and biostable therapeutic insulin.
