Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 95% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The ED₅₀ as determined by stimulation of IL-8 production using human PBMC is less than 10 ng/mL, corresponding to a specific activity of > 1.0 × 10⁵ IU/mg.

Endotoxin

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

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

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.
