Description
Thermo Scientific Glu-C Protease, MS Grade, is a highly specific endoproteinase use to improve sequence coverage in mass spectrometry protein identification applications.Features of Glu-C Protease, MS Grade:
• Complementary to tryptic digests—hydrolyzes proteins specifically at the carboxyl side of glutamic acids
• Increased sequence coverage—better protein characterization results from overlapping peptides with complementary sequence coverage and chromatographic, ionization and fragmentation properties
• High specific activity—greater than 500 units/mg protein
• N-terminal arginine cleavage specificity—at least 90% for a complex protein sample
• Stable—provided in a lyophilized format
Product Details
This Glu-C is a mass spectrometry (MS)-grade serine protease isolated from Staphylococcus aureus. Glu-C can be used alone or alongside trypsin or other proteases to produce complementary protein digests for peptide mapping and protein sequencing. Glu-C protease is suitable for either in-solution or in-gel digestion workflows. This Glu-C enzyme is packaged lyophilized (5 x 10 µg).
The endoproteinase Glu-C, also referred to as V-8 Protease, specifically cleaves the carboxyl side of glutamic residues when reactions are carried out in ammonium bicarbonate and ammonium acetate buffers, generating a limited number of peptide fragments. Cleavage can also occur at both glutamic and aspartic residues in phosphate buffers. Glu-C can efficiently digest protein in 5-18 hours at 37°C. Glu-C Protease remains active under denaturing conditions such as 2M urea, 1M guanidine·HCl, 0.1% SDS, 2% CHAPS and 20% acetonitrile. Glu-C activity is optimal at pH 8. This lyophilized enzyme has a mass of 27 kDa and is stable for 1 year when stored at -20°C.
Applications
• Improved sequence coverage of protein digests
• In-solution digestion of proteins
• In-gel digestion of proteins
