In Western Blot, bands at 85 kDa and 107 kDa are observed, representing different isoforms of ROBO4 protein.
Suggested positive control: HUVEC lysate, antigen standard for ROBO4 (transient overexpression lysate).
Roundabouts (ROBO) are cell-surface receptors that mediate repulsive signaling mechanisms at the central nervous system midline. However, ROBOs may also mediate attraction mechanisms in the context of vascular development. ROBO4 is a novel roundabout protein which is restricted in expression to endothelial cells in vitro and sites of angiogenesis in vivo. Because it is not expressed on normal endothelial cells, in vivo, it is a promising tumor endothelial marker.
