Ni-Penta Agarose, Chemical Stable

• Cat#No#: AC-002I
• Product Overview: Chemical-Tolerant Ni-Penta Agarose is a new immobilized metal ion affinity chromatography (IMAC) medium precharged with nickel ions, designed mainly for purification of low abundant proteins or challenging proteins in conditions where EDTA, DTT, β-ME, and other stabilizing agents are necessary for maintaining protein stability and integrity.
  The nickel ion binds very strongly to the matrix support in complex with a proprietary pentadentate chelating ligand, which immobilizes the nickel ion through 5 sites to form a homogeneous, chemical-stable structure. This characteristic nickel ion bonding on the Ni-Penta resin provides excellent resistance to EDTA, NaOH, β-ME, and other reagents that are restricted in the purification protocol using conventional NTA- and IDA- functionalized resins.
• Characteristic: EDTA-resistant
  High selectivity for high purity
  Retained high 6xHis affinity in various buffers
  Well suited for direct capture of secreted polyHis-tagged proteins from eukaryotic cell culture supernatant
  Recharge-free with minimal nickel ion leakage
  Requires less imidazole
  NaOH-tolerant
  Versatile, ready-to-use with convenient formats
• Applications: Purification of secreted His-tagged proteins directly from eukaryotic cell culture supernatants
  Purification of His-tagged proteins that require presence of EDTA, DTT, β-ME, and other agents for maximum protein stability and integrity
  Repetitive uses of the column that require clean-in-place with NaOH but no nickel recharge
  Restricted imidazole amount in the elution buffer due to the requirements in downstream applications or the target protein's sensitivity to imidazole
