Active Protein Note

Protein activity can be an ambiguous term. Please refer to the data sheet or inquire with Technical Support to determine the definition of activity for this product.

Molecular Weight Information

Approximately 17.5 kDa protein containing 158 amino acid residues.

Biological Activity

Fully biologically active when compared to standard. The Specific Activity is >=2.0 *107 IU/mg as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D.

Endotoxin Level

Less than 1EU/ug of rHuTNF-alpha as determined by LAL method.

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 degree C. Further dilutions should be made in appropriate buffered solutions.

Other Notes

Small volumes of tnfa active protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
