Recombinant Oxyopes takobius Oxyopinin-4a

Disrupts cell membranes through the formation of pores (Probable) . Has antibacterial activity against Gram-positive bacteria S.aureus (MIC=10 µM) and B.subtilis (MIC=0.5 µM) as well as Gram-negative bacteria P.fluorescens (MIC=1 µM) and E.coli (MIC=0.5 µM) . Has hemolytic activity against human erythrocytes (EC (50) =7 µM)

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
