Description

Utilize the tendency of iminodiacetic acid (IDA) to form a complex with metal ions, loaded with divalent metal ions by chelation.

• High efficiency, resin-based affinity columns separate or purify many enzymes and other proteins
• Utilize the tendency of iminodiacetic acid (IDA) to form a complex with metal ions, such as Zn2+, Ni2+ and Cu2+
• Column is loaded with divalent metal ions by chelation
• Peptides and proteins containing histidine residues will normally adsorb to these chelated ions at a neutral pH
• Retained compounds can be eluted with buffer containing imidazole or glycine
• A decreasing pH gradient can be used for elution purposes as well
• For successful use of this retention mechanism, select the proper metal ions for chelation and an elution buffer to desorb the analytes
• Applications: immunoglobulins, transferrin, lectins, milk proteins, membrane proteins and peptides
