The first peer-reviewed PC/PPQ framework for MCSGP. 95% IPC reduction, 73% PMI reduction, 96% gross-to-gross yield — validated at GMP commercial scale on Bachem Bivalirudin.
Eisenhuth, R. & Müller-Späth, T. — Processes, 2025 (Open-Access)
First peer-reviewed AIEX MCSGP for therapeutic siRNA. Yield improved from 80% to 93% on a sugar-conjugated siRNA sense strand — software-aided method development enabled fast batch-to-MCSGP transfer. Throughput increased 87%.
Weldon et al. Org. Process Res. Dev. 2025, (Open-Access)
Proof-of-concept MCSGP for AAV2 polishing. Full capsid content increased from 30% to 68% (ddPCR) after six cycles — with +20.6% yield, +23% productivity, and 27% reduced buffer consumption vs batch AEX. AutoPeak® PAT validated against cryo-TEM and ddPCR.

The foundational MCSGP process design demonstrates continuous countercurrent operation with solvent gradients for biomolecule purification.
Introduction of the MCSGP continuous chromatography concept presents process principles and demonstrates 10-fold productivity gains over batch chromatography.
Counter-current multi-column chromatography with modifier gradients establishes theoretical foundations for the MCSGP technology.
The foundational PhD thesis presents comprehensive development of countercurrent chromatographic purification processes that established the MCSGP technology.
Purification is where oligonucleotide yield is lost, and the synthesis has to be sized to cover it. Converting a reversed-phase batch method for a GalNAc-conjugated gapmer to twin-column MCSGP lifted recovery from 52.7% to 91.6% at the same purity — enough to shrink the synthesis step by 42.5% for the same daily output.
An established anion exchange batch method for a conjugated siRNA sense strand, converted to continuous twin-column MCSGP: 13 cycles, 27 product elutions, and yield up from 80% to 93% at unchanged purity — plus a software-aided route from batch chromatogram to running method.
Continuous chromatography is already in production use, but there was no published account of how to validate it for a regulatory filing. This study provides one, working through Process Characterization and Performance Qualification for MCSGP on commercial-scale Bivalirudin purification: 34 parameters assessed, four tested, one critical.
Green solvents have always cost the peptide industry recovery. This study shows the loss is a property of batch chromatography, not of the solvent: run the same green eluent counter-currently and the yield comes back.
