DiR is a near-infrared fluorescent carbocyanine dye specifically designed for cell membrane labeling in both in vivo and in vitro applications. When applied, DiR diffuses laterally, effectively staining the entire cell. Its unique properties make it suitable as both an anterograde and retrograde tracer for neurons. Additionally, DiR can be combined with other tracers for multi-color studies and is useful for near-infrared imaging.
