Achieve high resolution separations across exceptionally broad molecularweight ranges Low ionic strength eluents (NA.NA5 M) can utilize a hydrophobic interaction component to alter the selectivity of Superose for some lipids, peptides, and small aromatic compounds High performance gel filtration media specially designed for preparative purification of biomolecules. Superose 6 is designed for highresolution chromatography. Superose 6 prep grade permits easy, efficient scaleup to preparative separations. Superose 12 is for high resolution purification of proteins from 1 × 1NA3 to 3 × 1NA5 molecular weight, while Superose 12 prep grade is useful for preparative purification of these higher molecular weight proteins.
