Specifications for CD120a (TNF-RI) Antibody, anti-human, REAfinity™


Clone REA252 recognizes the extracellular part of the membrane-bound and soluble form of the CD120a antigen, a 55 kDa type I transmembrane glycoprotein also known as tumor necrosis factor receptor type I (TNF-RI) or p55. CD120a belongs to the TNF receptor superfamily and is mainly expressed by monocytes, macrophages, and neutrophils. It is also expressed by a variety of cell lines, tumor cells, and normal cell types including T cells, endothelial cells, hepatocytes, chondrocytes, and fibroblasts. Binding of TNF-α to its main receptor CD120a triggers signaling which is extremely complex, leading to both cell death and survival signals. Sustained activation of TNF signaling has been implicated in the pathogenesis of a wide spectrum of human diseases, including cancer, osteoporosis, sepsis, diabetes, and autoimmune diseases such as multiple sclerosis, rheumatoid arthritis, and inflammatory bowel disease.
Additional information: Clone REA252 displays negligible binding to Fc receptors.
