AbFluor™ 647 free acid is a kind red-fluorescent dye. It can produce bright fluorescence. The most distinct feature of the AbFluor™ 647 free acid is its superior signal-to-noise ratio of combination of antibody in immune fluorescence reaction. At the same time, compared with Alexa Fluor 647, AbFluor™ 647 free acid has few charge, which will not affect the specificity of the antibodies combination. So it is an ideal fluorescent dye.

AbFluor™ 647 free acid molecular weight is 1263. Abbkine supplies below price/size for your choice: $560/5 mg, $4480/50 mg.

The AbFluor™ 647 free acid has below features:
• λEX/λEm: 650/665 nm
• Extinction coefficient: 240, 000
• Provide the same or better fluorescence and photostability as Alexa Fluor 647, Cy5, DyLight™ 649.
