| Outline | <Protein Engineering><Amino Acid Sequencing Analysis Reagent><Enzyme for sequence analysis>Cleavage of polypeptide chains by protease is performed under a mild condition and, therefore, modification (oxidation, halogenation, deamidation, etc.) of side-chain amino acid residues does not occur, and peptides containing the groups (binding sites in carbohydrate chains, lipids, phosphate, sulfuric acid, etc.) for modification are usually recovered in a complete form at a good yield. Segments with good reproducibility can be obtained under identical conditions of digestion. Highly substrate-specific enzymes are used for the primary structure analysis of proteins, because it is possible to roughly predict the number of fragments and their average sizes from amino-acid composition, and more importantly, because it is possible to avoid complex isolation due to partial (nonspecific) cleavages.This enzyme specifically cleaves the N-terminal end of aspartic acid residue in proteins and peptides.The solution after preparation should be stored -20 degrees centigrade.Specificity: Reaction rate after 1 hour using glucagon as a substrate: min 90% |
