Webion exchange chromatography. Stable complexes and their component proteins can be separated on the basis of their net charge by ion-exchange chromatography. If a protein has a net positive charge at pH 7, it will usually bind to a column of beads containing carboxylate groups, and can then be eluted by increasing the concentration of sodium ...

Webques, users can alter various parameters. In the case of ion exchange chromatography, anion-exchange media (Q-Sepharose and DEAE-cellulose) or cation-exchange media (S-Sepharose and CM-cellulose) are available. With either, users define the method of elution as either a “salt gradient” or “pH gradient”. With salt gradient selected, WebWeak anion exchangers function poorly above a pH of 9 and weak cation exchangers begin to lose their ionization below pH 6. When working with weak ion exchange resins such as diethylaminoethyl … WebGenerally Sepharose is the result of evolution of Sephadex.
