Description

General description

Native endoproteinase Glu-C from Staphylococcus aureus. Serine protease that specifically hydrolyzes peptide bonds at the carboxylic side of glutamic acid and aspartic acid residues. Inhibited by DFP and α₂-macroglobulin. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.

Preparation Note

Following reconstitution, aliquot and freeze (-20°C) for long term storage or refrigerate (4°C) for short term storage. Stock solutions are stable for up to 2 days at 4°C or for up to 1 month at -20°C.
