Immobilized Metal Affinity Chromatography (IMAC) is based on the interaction between His-tag proteins and transition metal cations.

ABT is the only company to offer a solution for every His-tag protein:
1. The widest selection of metal chelating beads (4 different metals).
2. Two different degrees of loading (high and low density).
3. Three different formats to optimize the recovery of the specific biomolecules.
