Product name

PerCP anti-human TNF-α

Antibody type

Monoclonal

Antigen

E. coli-expressed, recombinant human TNF-α

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.
