Fe-NTA MagBeads


MagBeads
Immobilized metal affinity chromatography, or IMAC, has been employed for many applications making use of its versatile interaction with aromatic nitrogens and phosphates. To this end, NTA matrices have been loaded with a broad range of transition metals, as optimized for the individual interaction. Magnetic beads are ideal for protein purification from dilute supernatants and for pull-down experiments. Fe-NTA MagBeads are often used for the purification of phosphorylated proteins. Alternative matrices are Al-, Ga- or Zr-NTA. PureCube Fe-NTA MagBeads are delivered as a 25% suspension.

Purification of phosphorylated proteins

IMAC methods, in particular Fe-NTA or Ga-NTA, have been widely used to enrich phosphorylated proteins and phosphopeptides as part of the sample preparation for mass spectrometry (1,3,4). Under certain circumstances other transition metals, such as zirconium or aluminium have also been loaded on NTA or IDA matrices for enrichment (5). Magnetic beads have proven to be useful for this kind of sample preparation (2) in a similar manner to their agarose resin counterparts.
