PL-SCX is a macroporous PS/DVB matrix with a very hydrophilic coating and strong cation exchange functionality. The manufacturing process is controlled to provide optimum density of strong cation-exchange moieties for analysing, separating, and purifying a wide range of biomolecules from small peptides to large proteins.

Supplier: VARIAN

The PL-SAX media are well suited for anion exchange HPLC separations of proteins, peptides, and deprotected synthetic oligonucleotides. Denaturing conditions of temperature, organic solvent, and high pH levels are used for the oligonucleotide separations.
