AbFluor™ 660 free acid is a kind of fluorescent dye which is critical in far infrared and near infrared spectral range. The emission wavelength is at about 685 nm. Though the maximum absorption wavelength of AbFluor™ 660 free acid is at 660 nm, it can be excited by 633 or 635 nm laser. Compared with the Alexa Fluor660 dye, AbFluor™ 660 free acid can produce brighter fluorescence, and have better light stability, so it is the ideal dye for laser confocal and single molecular imaging.
AbFluor™ 660 free acid molecular weight is 888. Abbkine supplies below price/size for your choice: $560/5 mg, $4480/50 mg.
The AbFluor™ 660 free acid has below features:
• λEX/λEm: 663/682nm
• Extinction coefficient: 100, 000
• Provide the same or better fluorescence and photostability as Alexa Fluor® 660, Allophycocyanin (APC).
