Human peripheral blood lymphocytes were left un-stimulated (right) or stimulated with Cell Activation Cocktail (with Brefeldin A) (Cat. No. 423303) for 6 hours (left) were surface stained with anti-human CD3 (clone UCHT1) Brilliant Violet 421™. Cells were then fixed, permeabilized, and intracellularly stained with anti-human TNF-α (clone W19063E) Spark Blue™ 515. Data shown is gated on the lymphocyte population.

Description

TNF-α is secreted by macrophages, monocytes, neutrophils, T cells (principally CD4+), and NK cells. Many transformed cell lines also secrete TNF-α. Monomeric human TNF-α is a 157 amino acid protein (non-glycosylated) with a reported molecular weight of 17 kD. TNF-α forms multimeric complexes; stable trimers are most common in solution. A 26 kD membrane form of TNF-α has also been described. TNF-α binding to surface receptors elicits a wide array of biological activities including: cytolysis and cytostasis of many tumor cell lines in vitro, hemorraghic necrosis of tumors in vivo, increased fibroblast proliferation, and enhanced chemotaxis and phagocytosis in neutrophils.
