Protein Ark’s ProSEC Size Exclusion Columns (SEC) utilize a high performance rigid resin derived from a co-polymer of Dextran and Agarose. We offer 2 different column sizes: 16/60 and 26/60 columns with Superdex™ S75 pg and Superdex™ S200 pg behaviour. Our ‘6-600’ HR acrylic columns have a protein separation range within 6kDa to 600 kDa and the ‘3-70’ HR acrylic columns have a protein separation range within 3kDa to 70kDa. Both these HR acrylic columns are ideal for high definition preparative protein polishing steps using all aqueous buffers, at room temperature and in the cold room.
