Reversed-Phase MCSGP for GalNAc-Conjugated Oligonucleotides

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.

Oligo Purification 27 Aug 2026

Continuous Anion Exchange Purification of a Conjugated siRNA

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.

MCSGP Process Validation: Characterization and PPQ at Commercial Scale

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.

Acetonitrile- and TFA-Free Peptide Purification with MCSGP

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.
