HMBR (Cat No.:I044136) is a small organic fluorophore used as a chromophore in bioimaging and fluorescent protein labeling. It is particularly known for binding with engineered proteins such as modified yellow fluorescent proteins (YFPs), where it functions as a non-fluorescent ligand that fluoresces upon complex formation. HMBR exhibits green fluorescence and is often utilized in live-cell imaging and optogenetic tools due to its reversible binding and low toxicity. Its applications span cell tracking, protein interaction studies, and biosensor development, offering precise control in spatiotemporal biological imaging systems.
