Recombinant lysine endopeptidase (Lys-C) cas *-05-8 I. Product introduction Lysyl Endopeptidase (EC 3.4.21.50) belongs to a serine protease that specifically cleaves peptide bonds at the carboxy terminus of lysine residues. Lysyl endo-enzyme can be widely used in various biotechnological processes, such as: proteolysis to produce peptides; proteolysis; GLP-1 drug preparation.The optimum reaction pH was 9.0~9.5, and the isoelectric point was pH 6.9~7.0.The optimum reaction temperature was 30~37℃, and the stability decreased above 50℃.The stability of this enzyme was good. After incubation in 4mol/L urea or 0.2%SDS solution at 30℃ for 6h, the biological activity did not decrease.Biological activity was inhibited by DFP, PMSF and TLCK. II. Product characteristics Source: E. coli Character: white or off-white lyophilized powder Specific activity: ≥1AU/mg Pro Purity (SDS-PAGE) : single main band Specificity: specific cleavage of lysine residues III. Product use Used for the production of biological products, such as insulin and analog production, GLP-1 analogue production; protein mass spectrometry, sequencing, peptide mapping analysis; production of small molecular proteins or peptides etc. Iv. Recommend Usage It is recommended to use 20-50mM Tris HCl, pH 8.5-9.5 system, enzyme: fusion protein = 1-100au: 1g, optimal pH 9.0-10.0, optimal temperature 25-37 ℃, reaction time 2-24h. After dissolving, repackage and store under - 15 ℃.Inorganic salts above 0.1M have a certain effect on the enzyme activity, and it is recommended to carry out the enzyme digestion reaction after desalting. If it is not possible to desalinate, it is recommended to increase the amount of enzyme and extend the digestion time. V. Storage stability The lyophilized powder of this product can be stably stored for at least 24 months at -15℃. When the Tris-HCl buffer was formulated into an enzyme solution, it can store at -20 ℃ for 5 times without loss of activity. Vi. Pro....
