mFluor™ Red 780 Antibody Conjugates

Detect proteins and cells outside the visible spectrum with near-infrared mFluor Red 780 conjugates. mFluor Red 780 is highly photostable, reduces background noise by avoiding autofluorescence, and can be excited by standard red lasers found in flow cytometers and fluorescence microscopes (633 nm). mFluor Red 780 provides clear, reliable signals across a range of applications.

The dashed red line is the absorption spectrum of mFluor Red 780, while the solid line is its emission spectrum. For optimal outcomes in multiplex labeling experiments, choosing antibodies conjugated to fluorophores with minimal emission overlap is essential. Although its excitation peaks at 633, mFluor Red 780 has a broad excitation range making it versatile with many red and near-infrared lasers.

Applications in Research

mFluor Red 780 is a powerful research tool for several reasons:

  • 780 nm light is beyond the visible spectrum, giving mFluor Red 780 conjugates exceptionally low autofluorescence-induced background noise.
  • In multi-color experiments, the near-infrared emission of mFluor Red 780 shares overlap with very few other fluorophores.
  • mFluor Red 780 is easy to conjugate due to its variable reactive groups, water solubility, small size, and high stability. This enables efficient attachment to antibodies and biomolecules while maintaining functionality in experiments.
  • Compared to APC-Alexa Fluor® 750 tandem dyes, mFluor Red 780 is more photostable, making it readily available for fluorescence imaging applications.

mFluor Red 780 is stable and compatible with several techniques requiring fluorescent labeling, including:
