Purification of Synthetic Peptides by Counter-Current Chromatography (MCSGP) – An Economic Evaluation

High-pressure liquid chromatography employing the multicolumn countercurrent solvent gradient purification (MCSGP) process principle has been developed as a novel purification technology for peptides produced by chemical synthesis. MCSGP offers a step change in efficiency compared to batch HPLC processing. Peptides can be purified at preparative/production scale with significantly higher yield without compromising target purity. The process also allows an up to 10-fold higher productivity with typically 80% lower solvent consumption, providing an overall attractive economical production scenario and allowing pushing of the boundary of economic synthesis of long peptides to realize savings of millions of US dollars.
