法规信息
How can Product L6876, Lysozyme from chicken egg white, be reconstituted and can stock solutions be prepared?
For the lysis procedure, use a freshly prepared solution of 500,000 units/ml in 10 mM Tris-HCl, pH 8.0. The product is also soluble in water (10 mg/ml) yielding a clear to slightly hazy colorless solution. Aqueous solutions should be stable for at least one month when stored between 2-8 °C.
Can Product L6876, Lysozyme from chicken egg white, be inactivated by heat?
Solutions of Lysozyme may be inactivated by boiling for 40 seconds at 100°C at an alkaline pH.
What is the amino acid sequence of Product L6876, Lysozyme from chicken egg white?
Lysozyme is a single chain polypeptide of 129 amino acids. The amino acid sequence of chicken egg white Lysozyme is described in the Journal of Biological Chemistry, 238, 2698-2707 (1963).
Under what conditions can Product L6876, Lysozyme from chicken egg white, be used to lyse E. coli?
The following procedure is for the lysis of E. coli. It may be used as a guideline for other species.1. Incubate E. coli (strain ATCC 37017) bearing the pBR322 plasmid overnight in Terrific Broth (Product No. T 0918) with 25 μg/ml tetracycline (Product No T 3383) and 25 μg/ml ampicillin (Product No. A 9518).2. Centrifuge 1-2 ml samples of the overnight culture.3. Resuspend the pellets in 350 μl of STET buffer (10 mM Tris-HCl, pH 8.0, with 0.1 M NaCl, 1 mM EDTA, and 5% [w/v] TRITON® X-100).4. Add 25 μl of a freshly prepared lysozyme solution (500,000 units/ml in 10 mM Tris-HCl, pH 8.0).5. Mix by vortexing for 3 seconds.6. Incubate the lysis mixture for 30 minutes at 37 °C7. After incubation, place the tube containing the lysis mixture in a boiling water bath for exactly 40 seconds.8. Centrifuge the lysis mixture at 14,000 x g.9. Remove the pellet (cell debris) from the tube using a sterile toothpick.10. Plasmid DNA from the supernatant may then be purified and analyzed.
