Recombinant Human Tumor necrosis factor alpha CRP0806 1mg Please Inquiry


  • Product Overview
  • Tumor necrosis factor alpha-1a or TNFalpha-1a is a non-glycosylated cytokine produced from E. coli using rDNA technology. The protein consists of three identical polypeptide chains of 158 amino acids combined to form a compact, bell-shaped homotrimer. The individual subunits have a relative molecular mass each of 17.484 kDa.
  • Specificity
  • The ED50 as determined by the cytolysis of murine L929 cells in the presence of Actinomycin D is less than 0.03ng/ml, corresponding to a Specific Activity of 3.0 x 107 IU/mg.
  • Endotoxin
  • Less than 0.01ng/ug (0.01IEU/ug) determined by LAL test.
  • Purity
  • >95% by SDS-PAGE and SEC-HPLC .
  • Storage
  • Lyophilized samples are stable for up to twelve months from date of receipt at -20oC to -70oC. Aliquot to avoid repeated freeze-thaw cycles.
  • Reconstitution
  • It is recommended to reconstitute the lyophilized TNF alpha-1a in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

  • Antigen Description
  • TNF-alpha is a homotrimer with a subunit molecular mass of 17 kDa and that it plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, and autoimmune diseases; and in viral, bacterial, fungal, and parasitic infections. Besides inducing hemorrhagic necrosis of tumors, TNF was found to be involved in tumorigenesis, tumor metastasis, viral replication, septic shock, fever, inflammation, and autoimmune diseases including Crohn’s disease, and rheumatoid arthritis as well as graft-versus-host disease.
