| Purity (HPLC) | ≥ 97.0% (RP-HPLC) |
| Solubility | It is recommended to reconstitute the lyophilized Lysostaphin in 20mM sodium acetate, pH 4.5, for optimal stability, which can then be further diluted. |
| Stability | 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 three weeks and for future use below -18°C. |
| Appearance | Sterile Filtered lyophilized powder. |
| Specific Activity | ≥ 3,000 U/mg |
| Biological activity | 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 |
| Formulation | The protein was lyophilized without any additives. |
| Identification (RAMAN) | Conforms to Reference |
