Protein Purity
> 95% as determined by SDS-PAGE and HPLC.
Endotoxin< 1.0 EU/μg of the protein as determined by the LAL method.
FormulationLyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, 5% trehalose.
ReconstitutionReconstitute the lyophilized protein in sterile deionized water containing 0.1% BSA. The product concentration should not be less than 100 μg/ml. Before opening, centrifuge the tube to collect powder at the bottom. After adding the reconstitution buffer, avoid vortexing or pipetting for mixing.

Storage & Solubility Information
ShippingIn general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
StorageLyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
