Lysostaphin, an endopeptidase specific for the cell wall peptidoglycan of staphylococci, is an extremely potent anti-staphylococcal agent. Lysostaphin is used as a research and diagnostic tool. Because it lyses staphylococci efficiently, it is widely used when preparing staphylococcal DNA or other cellular components for genetic and biochemical studies and for the preparation of protoplasts for transformation. Preparation and analysis of bacterial DNA has become a powerful tool used by clinical and other microbiologists in epidemiological studies aimed at tracing sources of infection or bacterial contamination.?
Lysostaphin, EC 3.4.24.75, Glycyl-glycine endopeptidase.
Lysostaphin Recombinant produced in E.Coli is a non-glycosylated polypeptide chain having a molecular mass of 26.92 kDa.
Escherichia Coli.
Sterile Filtered lyophilized powder.
The protein was lyophilized without any additives.
Lyophilized Lysostaphin although stable at room temperature for 2 weeks, should be stored desiccated below -18°C. Upon reconstitution Lysostaphin can be stored at 4°C up to 3 weeks and for future use below -18°C.
Please prevent freeze-thaw cycles.
It is recommended to reconstitute the lyophilized Lysostaphin in 20mM sodium acetate, pH 4.5 for optimal stability, which can then be further diluted to other aqueous solutions such as 200mM Tris HCL pH-8 for optimal activity.?
97% as determined by RP-HPLC.
Assessed by the decrease in turbidity of a suspension of heat-killed Staphylococcus aureus at pH-8, 30°C. ?Lysostaphin is a zinc enzyme therefore EDTA is an inhibitory factor.
Determined to be?3,542 units/mg.
