His Prepacked Columns

His Prepacked Columns

  • BrandCommaX

biocomma® CommaXTM His prepacked columns are packed with highly cross-linked Poly(methyl methacrylate) beads which are coated with a propriety hydrophilic layer, then grafted with IDA ligands which donate binding sites to Ni2+ ions, forming an immobilized metal affinity chromatography (IMAC) medium for purifying recombinant proteins with polyhistidine tags.

Recombinant proteins with polyhistidine tags are retained due to the formation of complex compounds between their polyhistidine tags and immobilized Ni2+ ions. Impurity proteins without polyhistidine tags are washed off. The target proteins are eluted with an imidazole buffer solution.

CommaXTM His prepacked columns are available in 1 mL and 5 mL sizes.


  • Superior biocompatibility
  • Uncompromised biological activities
  • High purification yields
  • Moderate experimental conditions


  • Purification of recombinant proteins with polyhistidine tags from various express systems, such as bacterial, insect and mammal cells.
