Summary Tumor necrosis factor alpha (TNF-alpha), also called cachectin, is the best-know member of the TNF-family, which can cause cell death. This protein is produced by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes endothelial cells, smooth muscle cells and some transformed cells. TNF-alpha occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-alpha is glycosylated, but non-glycosylated recombinant TNF-alpha has comparable biological activity. The biologically active native form of TNF-alpha is reportedly a trimer. Rhesus macaque and human TNF-alpha show approximately 98 % homology at the amino acid level. Two types of receptors for TNF-alpha have been described and virtually all cell types studied show the presence of one or both of these receptor types.
Source Escherichia coli.
Molecular Weight Approximately 17.3 kDa, a single non-glycosylated polypeptide chain containing 157 amino acids.
Biological Activity Fully biologically active when compared to standard. The ED50 as determined by a cytotoxicity assay using murine L929 cells is less than 0.05 ng/ml, corresponding to a specific activity of > 2.0 × 107 IU/mg in the presence of actinomycin D.
Appearance Sterile filtered white lyophilized (freeze-dried) powder.
Formulation Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4, 5 % trehalose.
Endotoxin Less than 1 EU/ug of rRhTNF-α 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 °C. Further dilutions should be made in appropriate buffered solutions.
Stability and Storage Use a manual defrost freezer and avoid repeated freeze-thaw cycles.- 12 months from date of receipt, -20 to -70 °C as supplied.- 1 month, 2 to 8 °C under sterile conditions after reconstitution.- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
