Complete solutions for FPLC on a small footprint.
AZURA FPLC systems combine flexibility and reliability. The biocompatible and metal-free FPLC system is the perfect choice for your protein purification task.
IEC is a popular technique in protein purification. AZURA Bio Lab system supports all gradient methods including ion exchange chromatography.
Ion exchange chromatography separates molecules based on the overall charge of the protein. The proteins of interest have a charge opposite to that of the resin. In the case of cation exchange chromatography, proteins have an overall negative charge while binding to a cationic column (see image).
The initial binding takes place under low ionic strength conditions. Elution is achieved by a salt gradient. By increasing the salt concentration proteins with a weak negative charge elute first, while at higher salt concentrations proteins with a strong negative charge elute later. Ion exchange chromatography is frequently used for protein purification. A precise gradient formation is here one important parameter for a successful separation of proteins. AZURA Bio Lab System supports all gradient methods including ion exchange chromatography.
