Web4. Wash with 5 column volumes of high ionic strength limit buffer. (e.g. 1 M NaCl) 5. Wash with 10 column volumes of low ionic strength equilibration buffer. The column may now be further equilibrated in the starting buffer at the desired flow rate. 2.2 Buffer Selection Table 2 lists commonly used buffers for anion exchange chromatography ... WebJan 2, 2024 · When serum containing antibodies is applied to DEAE at a slightly acidic pH, the IgG flows through the column while most other serum proteins bind to the DEAE. This method is best performed using a batch method. The DEAE beads can be kept in a disposable syringe containing a polypropylene frit, a glass reactor containing a coarse …
Deae Sepharose Fast Flow Ion Exchange Column GE Healthcare
WebAnion Exchange Chromatography Anion exchange chromatography is practiced with either a strong or a weak anion exchange column, containing a quarternary ammonium ion, or with a weak anion exchanger, having either a tertiary or secondairy amine functional group, such as DEAE (diethylaminoethyl).A counter ion, often Cl-, maintains electroneutrality. … WebWhen working with weak ion exchange resins such as diethylaminoethyl (DEAE) or carboxymethyl (CM) resins, it is important to work within the supplier-provided working pH range. ...
