After reconstitution, Endoproteinase Glu-C from Staphylococcus aureus V8 (P2922) should be aliquoted and stored at -20°C for long-term storage. Stock solutions are stable for up to 1 month at -20°C. For short-term storage, solutions are stable for up to 2 days at 4°C. Avoid repeated freeze-thaw cycles.

Application
It is used for selective cleavage of proteins for amino acid sequence determination or peptide mapping.
Endoproteinase Glu-C from Staphylococcus aureus V8 has been used to digest reduced and alkylated cyclotides to produce linearized fragments.
Endoproteinase Glu-C from Staphylococcus aureus strain V8 is a serine protease used for selective cleavage of proteins for amino acid sequence determination or peptide mapping . Product P2922 has been used to linearize cyclic peptides in C. ternatea leaf extract.
Biochem/physiol Actions
Staphylococcus strain V8 protease specifically cleaves peptide bonds on the carboxyl side of aspartic and glutamic acid residues when used in phosphate buffer. When used in ammonium bicarbonate buffer or ammonium acetate buffer cleavage is restricted to the carboxyl side of glutamic acid residues only. The enzyme exhibits maximal activity from pH 4.0 to 7.8. If hemoglobin is used as the substrate, maximal activity is at pH 4.0. The maximal activity is at pH of 7.8 when casein is the substrate.

We reconstituted the 50 µg vial in 1200 µL of water for injection to obtain a concentration of ≥ 20 IU/mL. We used 200 µL, leaving 1000 µL. Should the remaining solution be stored at 2–8 °C, or would aliquoting and freezing at –20 °C be more appropriate?
