Figure 1: TNF-α, Soluble (human) (rec.)(AG-40B-0074) induces NF-κB dependent genes. Methods: Endothelial cells (HUVEC) are incubated for 1h in the presence of BAY 11-7082 (AG-CR1-0013) and then treated with TNFα (20ng/ml) (red bar) or incubated with TNFα (20ng/ml) (in the presence or absence of TNF-R1 (human):Fc (human) (rec.) (0.5µg/ml) (blue and gray bar, respectively). TNFα-induced genes expression such as E-Selectin or MCP-1 are tested by flow cytometry.

Description
Tumor necrosis factor (TNF, cachexin or cachectin and formerly known as tumor necrosis factor-α) is a cytokine involved in systemic inflammation and is a member of a group of cytokines that stimulate the acute phase reaction. The receptor TNF-R1 is activated by both the membrane-bound and soluble trimeric forms of TNF-α, whereas the receptor TNF-R2 only responds to the membrane-bound form of TNF-α (MultimericTNF-α (Prod. No. AG-40B-0019). Since the MultimericTNF-α mimics the membrane-bound form (forms oligomers higher than trimer), it is the only TNF-α protein that can activate the TNF-R2. For TNF-R1 activation, either "normal" TNF-α or MultimericTNF-α can be used.
