Notes
  • Storage Conditions: Supplied in dry format. Can be stored frozen in solution at -20°C for up to 2 weeks. A decrease in activity will occur if stored in solution. Use only freshly reconstituted protease for best results.
  • Endoproteinase AspN contains a O-linked carbohydrate on the protein. The protein appears as a single band by SDS-PAGE analysis.
  • Aspartic acid residues are strongly favored by Endoproteinase AspN in all buffer conditions we have examined (Tris-HCl, ammonium bicarbonate and potassium phosphate) (2).
