Samples that usually cause stripping of metal ions can therefore be added to the medium with retained protein-binding capacity and without pretreatment.

  • His Mag Sepharose excel is a magnetic IMAC medium precharged with nickel ions that are very strongly bound to a chelating ligand.
  • The medium enables an efficient and simplified workflow for capture, purification, and reproducible screening of histidine-tagged proteins.
  • Simplify small-scale purification and expression screening of histidine-tagged proteins secreted in eukaryotic cell culture.
  • Purify histidine-tagged proteins directly from samples that contain metal ion-stripping agents and save time and effort.
  • Increase target protein yield and decrease degradation through reduced and simplified sample handling.
  • Screen histidine-tagged proteins in parallel with high reproducibility and reliable results.
  • Capture histidine-tagged protein from different sample volumes; from low to high milliliter scale.
  • Simplify handling using visible and dense Sepharose-based magnetic beads.
  • Proteins are expressed and secreted into cell culture supernatants from eukaryotic cells such as insect cells or Chinese Hamster Ovary (CHO) cells.
  • The high density of the beads allows rapid capture by magnetic devices while the visibility of the beads ensures reliable collection of the bound histidine-tagged proteins during the purification procedure.
  • The base matrix is based on Sepharose medium with magnetite incorporated.
  • His Mag Sepharose is available as 10% medium slurry in three different pack sizes (2 x 1ml, 5 x 1ml, and 10 x 1ml) and can be used together with different test tubes and magnetic racks.
