Arg-C Endoproteinase, MS Grade

• Description: Arg-C is a specialized endopeptidase that hydrolyzes peptide bonds at the carboxyl side of arginine residues. It maintains efficiency even when arginine is adjacent to proline. This enzyme is frequently used in tandem with other proteases to increase sequence coverage in mass spectrometry workflows.
• Physical Appearance: Mass Spec Grade Arg C Protease is a lyophilized powder (containing 0.25 mg trehalose, 0.1 µmol cysteine, and 2 µmol CaCl2)
• Molecular Weight: 45 kDa
• Resuspension Buffer: Use 1 mM HCl with 2 mM CaCl2 for powder reconstitution.
• Storage: Maintain dry powder at -20 °C; reconstituted liquid is stable at -20 °C for up to 30 days.
• Shelf life: Store at -20 ℃ for up to12 months for lyophilized powder.
