Description
AlexaFluor®647 hydrazide can be used as a cell tracer and reactive dye to label aldehydes or ketones in polysaccharides or glycoproteins. AlexaFluor®647 is a bright far red fluorescent dye with excitation light, which is very suitable for 633 nm laser line. The AlexaFluor®647 dye used for stable signal generation in imaging and flow cytometry is water-soluble from pH 4 to pH 10 and is not sensitive to pH.

Detailed information about this AlexaFluor® hydrazide:
• Fluorophore label: AlexaFluor®647 dye
•Reactive group: hydrazide
• Reactivity: Aldehydes or base notes in polysaccharides or glycoproteins
• Ex / Em of conjugate: 649/666 nm
•Extinction coefficient: 250,000 cm-1M-1

Fluorescent Dye
Applications
Neural Tracing
Application Notes
AlexaFluor® hydrazide and hydroxylamine can be used as low molecular weight, membrane-impermeable cell tracers that can fix aldehydes. Compared with cell tracers derived from other spectrally similar fluorophores, they have brighter fluorescence and higher Light stability.
