外观（Physical Appearance）

Sterile Filtered White lyophilized (freeze-dried) powder.

纯度（Purity）

> 98 % by SDS-PAGE and HPLC analyses.

生物活性（Biological Activity）

Fully biologically active when compared to standard. The ED₅₀ as determined by anti-microbial activity against E.coli. is less than 30 μg/ml, corresponding to a specific activity of > 33.3 IU/mg.

内毒素（Endotoxin）

< 1.0 EU per 1μg of the protein by the LAL method.

制剂（Formulation）

Lyophilized from a 0.2 µm filtered concentrated solution in 20 mM PB, pH 7.4, 130 mM NaCl.

复溶（Reconstitution）

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
