Flamma® 496 Thiol

Flamma® Fluors 496 Thiol is inactive form of bright green fluorescent dye induced from fluorescein structure and used to generate a stable fluorescence signal in bioimaging. The thiol is attached to Flamma 496 fluorophore through a spacer. The maxima of Ex/Em values are at 494/520 nm, similar to that of Fluorescein. Flamma 496 might be excited using 488 nm laser line and displays excellent optical property. Flamma® Fluors 496 thiol can be labeled to biomolecules through a disulfide bond formation with thiol of cysteine residue or can be utilized as a reference standard for dye-conjugates.
