The ProPac 3R product line consist of two ion exchange columns (SCX and SAX). These columns are especially designed for protein and monoclonal antibody (mAb) analysis. The housing material is bioinert PEEK. The particles are monodisperse, non-porous 3µm divinylbenzene resins. The monodisperse particles have a consistent size distribution, resulting in improved packing and lot-to-lot reproducibility.
The 3Rs in the name of the product line stand for robustness, reproducibility and resolution.
Robustness:
Run-to-run reproducibility of Left: protein G salt gradient analysis on a ProPac 3R SAX column Right: NISTmAb salt gradient analysis on a ProPac 3R SCX column
Reproducibility:
Lot-to-lot reproducibility of Left: protein G salt gradient separation on a ProPac 3R SAX column Right: NISTmAb salt gradient separation on a ProPac 3R SCX column
Resolution:
Salt gradient analysis of Links: protein G using a ProPac 3R SSX column Rechts: infliximab using a ProPac 3R SCX column
Comparison of Left: Protein G separation on Propac 3R SAX, 3µm and a ProPac SAX 10µm columns using high-resolution 30-minute gradient method. Right: NISTmAb separation on MAbPac SCX-10, 10µm 4 x 250mm. ProPac 3R SCX, 3µm 4 x 100mm, and a competitor's SCX 3µm 4.6 x 100mm column using a high-resolution 25-minute gradient method.
Conclusion: The ProPac 3R IEX columns offer high resolution compared to other columnsdue to monodisperse 3µm particles. They are highly reproducible and robust,making them an outstanding product line for analysis of proteins and mAbs.
