Stabilized recombinant lysozyme
rLysozyme™ Solution contains a highly purified and stabilized recombinant lysozyme that can be used for lysis of Gram-negative bacteria, such as E. coli. The enzyme catalyzes the hydrolysis of N-acetylmuramide linkages in bacterial cell walls. The specific activity of rLysozyme (1700 KU/mg) for E. coli lysis is 250 times greater than that of chicken egg white lysozyme. rLysozyme is optimally active at physiological pH. Very small amounts of rLysozyme (3-5 KU/g cell paste) enhance the efficiency of protein extraction with BugBuster®, BugBuster HT, and PopCulture® Reagents. In the absence of protein extraction reagents, direct lysis of E. coli can be achieved by treatment of 1.0 gram cell paste with 45-60 KU rLysozyme. The product is supplied as a ready-to-use solution at a concentration of 30 KU/µl in 50% glycerol containing 50 mM Tris-HCl, 0.1 M NaCl, 0.1 mM EDTA, 1 mM DTT, 0.1% TRITON® X-100, pH 7.5. rLysozyme Solution is stable at -20°C. |
