Open the CIPO recordAbstract From the Canadian patent
Recombinant plasmids are described that carry the structural gene for human proinsulin in expressible form. The human proinsulin structural gene is fused to a functional transport sequence. Host organisms transformed by the recombinant plasmids express a preploinsulin product that is correctly processed to human proinsulin in vivo, and is transported across the host organism's cell wall. Following its recovery, in vitro methods are used to convert the human proinsulin to human insulin.
