Fully porous quaternary amine strong anion exchange suitable for oligonucleotides and proteins.

• Small particles deliver excellent chromatographic performance
• Wide range of particle sizes for flexible analysis and scale-up purification
• Exceptional stability for long column lifetime

PL-SAX for Biomolecules is ideal for the anion-exchange HPLC separations of proteins and deprotected synthetic oligonucleotides under denaturing conditions. The covalently linked strong anion exchange functionality extends the operating pH range, and the anion exchange capacity is independent of pH. For synthetic oligonucleotides, separations using denaturing conditions of temperature, organic solvent, and high pH are all possible.

PL-SAX for Biomolecules delivers improved chromatography for self-complementary or G-rich sequences that may associate to form aggregates or hairpin structures. The 5 μm material provides high efficiency separations of n and n-1 sequences.
