Product Introduction

Sodium 4-[2-[(1E,3Z,5E,7E)-4-Carboxy-7-[1,1-dimethyl-3-(4-sulfonatobutyl)-1,3-dihydro-2H-benzo[e]indol-2-ylidene]hepta-1,3,5-trien-1-yl]-1,1-dimethyl-1H-benzo[e]indol-3-ium-3-yl]butane-1-sulfonate is a complex cyanine dye known for its extended conjugated system, which facilitates strong absorption and emission in the visible spectrum. This compound features a sulfonate group that enhances water solubility, making it suitable for aqueous biological environments and enabling its use in fluorescence-based assays and imaging applications. The dye's structural design allows it to function effectively in Förster Resonance Energy Transfer (FRET) applications, where it acts as an energy donor or acceptor, depending on the experimental setup.
