Biopolymers including functional proteins such as enzymes are isolated and purified normally through several separation steps. The ion exchange chromatography is one of the important methods included in these steps. The carriers are obtained by chemically bonding cellulose and ion exchange groups.


Features
  • High exchange capacity for proteins as well as well as other polymers
  • Since they are available in the preswollen microgranular form, it makes acid or alkali treatment and removal of particulates are unnecessary. It can be used immediately after replacement with the buffer used.
  • The lot-to-lot variation is low, and high reproducibility.
