Peptides

Cation exchange chromatography is a useful technique for purification of many peptides. WorkBeads 40S, an agarose-based cation exchange resin, has proven to be an excellent tool for purification of therapeutic peptides from crude feeds following solid-phase synthesis or after recombinant expression, due to its high binding capacity and optimal flow pressure properties.
