标签(Tag)

None

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-α mediated cytotoxicity in the L-929 cells is less than 0.2 μg/mL, corresponding to a specific activity of > 5000 IU/mg in the presence of 0.25 ng/mL of rHuTNF-α.

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 concentrated 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.
