Features and Benefits

  • Includes ready to use reagents, columns, and a detailed protocol for affinity purification of FLAG fusion proteins.
  • ANTI-FLAG M2 Affinity Gel allows efficient binding of FLAG fusion proteins without the need for preliminary steps and calibrations.
  • Two alternatives for efficient elution conditions (by acidic conditions or by competition with FLAG peptide).


Sufficient for 3-5 uses of 1-ml affinity purification column.

Other Notes

Kit contains CelLytic™ M for cell lysis and protein extraction from Mammalian cells.
