robo4 Antibody (D-3) is a mouse monoclonal IgM kappa antibody that detects robo4 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). anti-robo4 antibody (D-3) is available as the non-conjugated form. robo4 protein plays a crucial role in regulating angiogenesis and vascular development, acting as a key player in maintaining endothelial cell integrity and function. robo4 is primarily localized in endothelial cells, where robo4 modulates interaction between cells and extracellular matrix, influencing processes such as cell migration and proliferation. The unique structure of robo4, characterized by distinct extracellular domains, allows specific interaction with Slit ligands, which are essential for repelling axonal growth during neural development. This interaction contributes to proper formation of neural pathways and highlights robo4′s importance in vascular biology, helping prevent excessive cellular migration that could lead to pathological conditions. Using anti-robo4 antibody (D-3) in research can provide valuable insights into mechanisms of endothelial function and broader implications of robo4 in both neural and vascular development.
