外观（Physical Appearance） |
Sterile Filtered White lyophilized (freeze-dried) powder. |
|
纯度（Purity） |
> 97 % by SDS-PAGE and HPLC analyses. |
|
生物活性（Biological Activity） |
Fully biologically active when compared to standard. The ED50 as determined by its ability to inhibit the TNF-alpha mediated cytotoxicity in the L-929 cells is less than 0.05 μg/mL, corresponding to a specific activity of > 2 × 104IU/mg in the presence of 0.25 ng/mL of rHuTNF-alpha. |
|
内毒素（Endotoxin） |
< 0.1 EU per 1μg of the protein by the LAL method. |
|
制剂（Formulation） |
Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4. |
|
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. |
