Specifications for CD181 (CXCR1) Antibody, anti-human, REAfinity™


Clone REA958 recognizes the human CD181 antigen, a multi-pass membrane protein also known as C-X-C chemokine receptor type 1 (CXCR1) or IL-8 receptor A (IL-8RA). CD181 is expressed as homodimer or heterodimer with CD182 (CXCR2) and found on granulocytes, natural killer (NK) cells, a subset of T lymphocytes, mast cells, monocytes, endothelial cells, megakarocytes, and oligodendrocytes. It is one of two high-affinity receptors for interleukin 8 (IL-8), a major mediator of immune and inflammatory responses implicated in many disorders, including tumor growth. IL-8, released in response to inflammatory stimuli, binds to the extracellular part of CD181. The ligand-activated intracellular signaling pathways results in neutrophil migration to the site of inflammation.
Additional information: Clone REA958 displays negligible binding to Fc receptors.
