TNF-a Tumor Necrosis Factor-Alpha Rabbit Recombinant Protein

• Description:

  Tumor Necrosis Factor-a Rabbit Recombinant consists of three identical polypeptide chains of 158 amino acids combined to form a compact, bell-shaped homotrimer. TNF-alpha was produced in E. coli is a non-glycosylated, polypeptide chain having a molecular mass of 17.4 kDa for the individual subunit. The TNF-alpha is purified by standard chromatographic techniques.

• Synonyms:

  Tumor necrosis factor; Cachectin; TNF-alpha; Tumor necrosis factor ligand superfamily member 2; TNF-a; TNF; TNFA; TNFSF2.

• Gene Name:

  Escherichia coli

• Sequence:

  [object Object]

• Purification:

  Greater than 95% as determined by (a) Analysis by RP-HPLC and (b) Analysis by SDS-PAGE.

• Bioactivity:

  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 30,000,000 IU/mg.

• Form:

  Sterile Filtered White lyophilized (freeze-dried) powder.

• Reconstitution:

  It is recommended to reconstitute the lyophilized Tumor Necrosis Factor-alpha in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

• Function:

  Cytokine that binds to TNFRSF1A/TNFR1 and TNFRSF1B/TNFBR. It is mainly secreted by macrophages and can induce cell death of certain tumor cell lines. It is potent pyrogen causing fever by direct action or by stimulation of interleukin-1 secretion and is implicated in the induction of cachexia, Under certain conditions it can stimulate cell proliferation and induce cell differentiation.

• Shipping Conditions:

  Available

• Storage Conditions:

  Lyophilized Tumor Necrosis Factor-a although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TNF-a should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA) .Please prevent freeze-thaw cycles.

• Other Gene Names:

  Tumor necrosis factor
