Recombinant Human and Porcine Trypsin

Polymun has proprietary yeast recombinant human and porcine trypsinogen that is autocatalytically activated to the active enzyme. These products are intended to replace trypsin derived from animal origin.

Recombinant human trypsin and recombinant porcine trypsin have defined activity (e.g. free of chymotrypsin or elastase activity without inhibitor treatment) and are free of animal tissue derived contaminants. They are valuable tools to improve both quality and safety in various cell culture applications, such as cell based therapy applications and industrial expression systems using cell culture hosts, as well as for manufacturing drugs and/or direct application as a drug.

Polymun is currently establishing GMP-conform manufacturing processes. You can order rhTrypsin and rpTrypsin as research reagents.

Polymun is open to strategic and/or financial partnerships for commercial development.
