    Purification of his-tagged protein on FPLC instruments
    Reagent Preparation

    A Purification under native conditions:

    • Native Lysis buffer: NaH2PO4 50 mM, NaCl 300 mM, Imidazole 10 mM, pH 8
      Optional: Add 1 tablet protease inhibitor cocktail to the Lysis Buffer.
      Tip: Lysis Buffer contains 10 mM imidazole to prevent binding of untagged proteins. If His-tagged proteins do not bind under these conditions, reduce the imidazole concentration to 1-5 mM.
    • Native Wash buffer: NaH2PO4 50 mM, NaCl 300 mM, Imidazole 20 mM, pH 8
    • Native Elution buffer: NaH2PO4 50 mM, NaCl 300 mM, Imidazole 250- 500 mM, pH 8

      Additional chemicals required: Lysozyme, Benzonase® nuclease,
      Optional: Protease inhibitor cocktail

    B Purification under denaturing conditions:
    • Denaturing Lysis buffer: NaH2PO4 100 mM, Tris base 10 mM, Urea 8 M, pH 8.0,
      Optional: Benzonase® nuclease (e.g. Merck Milipore, #707464)
    • Denaturing Wash buffer: NaH2PO4 100 mM, Tris base 10 mM, Urea 8 M, pH 6.3NaH2PO4 100 mM
    • Denaturing Elution buffer: NaH2PO4 100 mM, Tris base 10 mM, Urea 8 M, pH 4.5
      Tip: If the target protein is acid-labile, elution can be performed with 250-500 mM imidazole.
      Note: Due to urea dissociation, adjust the pH immediately before use.

    Assay Procedure

    Standard protocols for His affinity purification can be applied. Please also refer to the FPLC instrument manufacturer's instructions.

    Calculation of Results

    Analyze by SDS-PAGE, Bradford Assay or spectrophotometrically.
