Product Description

This product is prepared by labeling high quality F(ab’)2 fragment goat anti-mouse IgG, Fcγ fragment specific, with the far-red fluorescent dye CF®640R. The antibody has been adsorbed against human, bovine and horse serum to minimize cross-reactivity. CF®640R is a better alternative to Cy®5, Alexa Fluor® 647 and other spectrally similar dyes.  Learn more about CF®640R.

Advantages of CF®640R

  • A novel rhodamine-based dye spectrally very similar to Cy®5 and Alexa Fluor® 647
  • Much brighter than Cy®5 and at least as bright as Alexa Fluor® 647 when excited at 633 or 635 nm
  • Exceptional photostability: far more photostable than Cy®5 and Alexa Fluor® 647
  • More photostable than Atto 647N, a dye that has been extensively used in single molecule-based imaging
  • Extremely water-soluble and pH-insensitive.
