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. |
储存条件
