Descripciòn

Lysostaphin is an antistaphylococcal agent. Lysostaphin has activities of three enzymes namely, glycylglycine endopeptidase, endo-β-N-acetyl glucosamidase and N-acteyl muramyl-L-alanine amidase[1].

In Vitro

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.

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Lysostaphin Related Antibodies
In Vivo

Lysostaphin (5 mg/kg, intravenous injection, once daily for 3 consecutive days) effectively clears systemic Staphylococcus aureus (MSSA) infections in CF-1 mice[2].
Lysostaphin (50 mg/kg, intravenous injection, single dose) effectively clears Staphylococcus aureus (MSSA and MRSA) infections from the kidneys, spleen, and liver, but is not superior to repeated lower doses[2].
Lysostaphin (1 mg/kg, intravenous injection, once daily for 3 consecutive days) combined with Oxacillin (HY-B0925A) achieves the same antibacterial effect with a lower concentration of Lysostaphin. When combined with Vancomycin, low-dose Lysostaphin (1 mg/kg) similarly shows enhanced efficacy against MRSA[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

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)).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
