Product Overview:
SG-Lysine-C™ endopeptidase, from Lysobacter enzymogenes, is a serine protease highly specific in cleaving peptide bonds at the carboxy side of lysine. Highly purified preparations of SG-Lysine-C™ are chemically modified making the enzyme resistant to autolysis and stabilizing its enzymatic activity. SG-Lysine-C™ is supplied lyophilized in 5µg vials. The enzyme is typically reconstituted to a concentration of 0.25µg/ml. For fragmentation, the enzyme is added to the sample protein in a ratio of 1:100 to 1:20 (enzyme to protein, by weight) in a standard digestion buffer.
Application:
Digestion of proteins for sequence analysis. Suitable for sequencing applications.
Features:
Modified Lysine-C for sequence analysis. Resistant to autolysis and degradation. High Specificity, free from other known endopeptidases. Consistency of activity levels from lot to lot for reproducible digestions. Recommended SG-Lysine-C™ to protein ratio, 1:100 to 1:20.
