Clone REA442 recognizes the human CD166 antigen, a single-pass type I membrane protein also known as activated leukocyte cell adhesion molecule (ALCAM). CD166, a member of the immunoglobulin superfamily and a ligand for the lymphocyte antigen CD6, mediates homophilic and heterophilic adhesion. It is expressed on activated leukocytes T cells, B cells, monocytes, hematopoietic stem cells (HSCs), metastasizing melanoma, neuronal cells, endothelial cells, hematopoiesis-supporting osteoblastic cell lines, and mesenchymal stem cells (MSCs). CD166 expression is pathologically correlated with aggressive disease in a variety of cancers including melanoma, prostate, breast, ovarian, esophageal, and bladder cancers. It is also a universal functional marker of murine and human HSCs and osteoblasts within the hematopoietic niche and it is involved in modulating HSC-niche interactions and HSC fate.
Additional information: Clone REA442 displays negligible binding to Fc receptors.
