Cy7 is a bright and photostable NIR probe spectrally similar to Alexa Fluor® 750, DyLight® 750, and IRDye® 750 dyes. Cy7 DBCO is a water-soluble hydrophilic dye that is typically required for minimal nonspecific binding and excellent brightness The reagent of choice for analysis. The fluorescence of Cy7 DBCO is pH-insensitive from pH 4 to pH 10 and produces minimal autofluorescence in biological samples in this spectral region. The fluorescence of this long-wavelength cyanine dye is invisible to the human eye, but is easily detected by most imaging systems.
