| 标签(Tag) | None | 
| 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) | The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.1 ng/mL, corresponding to a specific activity of > 1.0 × 107 IU/mg in the presence of actinomycin D. Fully biologically active when compared to standard. | 
| 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 PBS, pH 7.2. | 
| 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℃. Further dilutions should be made in appropriate buffered solutions. |
