TNF a produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 163 amino acids (77-233a.a.) and having a molecular mass of 18.1kDa. (Molecular size on SDS-PAGE will appear at approximately 18-28kDa). TNF a is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

Source

Sf9, Baculovirus cells.

Formulation

TNF a protein solution (1mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.

Purity

Greater than 90.0% as determined bySDS-PAGE.

Biological Activity

Measured in a cytotoxicity assay using L929 mouse fibrosarcoma cells in the presence of the metabolic inhibitor actinomycin D. 
The ED50 for this effect is ≤ 0.2 ng/ml.

More Info

  • Introduction

    Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that all stimulate the acute phase reaction. TNF is mainly secreted by macrophages.
    TNF causes apoptotic cell death, cellular proliferation, differentiation, inflammation, tumorigenesis and viral replication, TNF is also involved in lipid metabolism, and coagulation. TNF's primary role is in the regulation of immune cells.
    Dysregulation and, in particular, overproduction of TNF have been implicated in a variety of human diseases- autoimmune diseases, insulin resistance, and cancer.
