TNF-alpha/TNFSF2 Protein, Human (His)

Cat. No.: HY-P7416
Handling Instructions

TNF-alpha/TNFSF2 Protein, Human (His) is recombinant human tumor necrosis factor alpha (TNF-α) with his tag. TNF-alpha/TNFSF2 Protein, a pleiotropic cytokine, is one of the major mediators of inflammation and is involved in a number of infectious and parasitic diseases. It appears to be involved in blood-brain barrier, inflammatory, thrombogenic, and vascular changes associated with brain injury.

Tumor necrosis factor-α (TNF-α) is a pleiotropic cytokine produced by a wide variety of cell types of mostly hematopoietic, but also of nonhematopoietic, origin. TNFα is instrumental in the immune elimination of various infectious agents such as Candida albicans, Listeria monocytogenes, or mycobacteria and exerts potent proinflammatory effects, e.g. by inducing the expression of adhesion molecules such as VCAM-1, intercellular adhesion molecule 1 (ICAM-1), or E-selectin on endothelial cells and other cell types. Aberrant production of TNFα, however, has been also implicated in the pathogenesis of various diseases, such as rheumatoid arthritis, insulin-dependent diabetes-mellitus, sialoadenitis, and inflammatory bowel disease, in particular Crohn's disease[1][2].

  • Dilution Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
