• Relevance:

  Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids, thus producing hydrogen peroxide that may contribute to the diverse toxic effects of this enzyme. Is very active against L-Lys, L-Phe, L-Leu, L-Tyr, L-Trp, L-Arg, and L-Met, moderately active against L-His, L-cystine, and L-Ile, and slightly active against L-Gln, L-Asn, L-Ala, and L-Val. L-Glu, L-Ser, L-Pro and Gly are oxidized very slowly. Its activity on platelet aggregation is controversial. It has potent inhibitory activity on platelet aggregation induced by ADP and the thromboxane analog U46619, but not by thrombin, mucetin, ristocetin and stejnulxin, but it has also been shown to induce platelet aggregation through the formation of hydrogen peroxide. It binds to bacteria and shows antibacterial activities by generating hydrogen peroxide. Binding and antibacterial activities are higher against Gram-positive than against Gram-negative bacteria. May also have an ability to induce hemorrhage, hemolysis, edema, apoptosis.

• Endotoxin:

  Not test

• Purity:

  Greater than 85% as determined by SDS-PAGE.

• Activity:

  Not Test

• Bioactivity:

  Not Test

• Form:

  Liquid or Lyophilized powder

• Buffer:

  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.

• Reconstitution:

  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.

• Molecular Weight:

  60.6 kDa

• Storage Conditions:

  The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
