Specifications for DLL4 Antibody, anti-human, REAfinity™


Clone REA1065 recognizes the human delta-like4 (DLL4) antigen, which is a type I membrane protein belonging to the Delta/Serrate/Lag2 (DSL) family of Notch ligands. Notch signaling controls cell fate decisions and is involved in multiple developmental processes. Notch ligands are categorized into two subfamilies: the Jagged and the Delta ligand family. In mammals, five ligands (DLL 1, 3, and 4, Jagged 1 and 2) have been identified. DLL4 is highly expressed within vascular endothelial cells, thymic epithelial cells, and dendritic cell subsets and plays an important role for vascular development and homeostasis and thymic as well as peripheral T cell differentiation.
Additional information: Clone REA1065 displays negligible binding to Fc receptors.
