Biological Activity
Lysostaphin (16 μg/mL, 0-260 minutes) exerts its antibacterial effect by hydrolyzing the peptidoglycan cross-linkages of Staphylococcus aureus, weakening the mechanical strength of the cell wall and causing structural damage[3].
Product Information
Molecular weight: 27 kDa
Effective pH range: 5.0-8.0
Instructions
Can be dissolved in ddH2O at a concentration of 1 mg/mL. Fresh preparation is recommended. Or dissolve in buffer according to specific experimental references.
Notes
PCMB, PMSF, DTT, etc. have no obvious effect on enzyme activity at 1 mM. Ba2+, Mn2+, Ca2+, Mg2+ and EDTA show a certain degree of inhibitory effect on enzyme activity at a concentration of 1 mM.

Animal Model:Systemic infection model in CF-1 mice induced by methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA)[2]
-
Dosage:1, 5, 25, 50 mg/kg
-
Administration:Intravenous injection (i.v.), single high-dose administration: 25 mg/kg or 50 mg/kg intravenous injection, single dose; Once daily administration: 1 or 5 mg/kg, once daily for 3 days.
-
Result:Cleared MSSA from the blood and organs of mice (5 mg/kg for 3 days). Cleared MSSA and MRSA from the kidneys, spleen, and liver (A higher single dose of 50 mg/kg). Improved effectiveness and allowed reduction of the lysostaphin dose to 1 mg/kg for MRSA infections (Combined with Oxacillin (HY-B0925A) or Vancomycin (HY-B0671)).
