Overview
Ion exchange chromatography is a separation method based on the different charges of the protein under certain pH conditions. Due to most of biological molecules with acidic or alkaline groups, anion exchange matrix combined with the negatively charged proteins and cation exchange matrix binds positively charged proteins, and its charged properties and quantity can be changed by adjusting the pH of buffer solution, so that the weak binding can be eluted first, and the strong binding can be eluted later, so as to achieve the purpose of separation and purification.
Today we will introduce Q Tanrose 6FF which is a strong anion exchange medium

Points for Attention
1. The maximum operating pressure shall not exceed 0.3mpa;
2. Avoid using oxidants, anionic detergents and anionic buffers;
3. It is recommended to use 0.22μm or 0.45μm filter membrane for water and buffer before use;
4. Samples are recommended to be centrifuged or filtered with 0.22μm or 0.45μm membrane before loading to reduce impurities, improve protein purification efficiency and prevent from blocking the column
