NovaFluor Blue 610 dyes are available with two different levels of brightness: NovaFluor Blue 610-30S and NovaFluor Blue 610-70S, allowing for differential matching of the dye brightness to the antigen density or abundance, without panel redesign. NovaFluor Blue 610-70S dye is the brighter dye.

NovaFluor Blue 610-70S dye can be used to replace PE/Dazzle 594, BD Horizon PE-CF594, or PE-Texas Red dye using the 488 nm blue laser line for excitation. As compared with these PE tandem dyes, NovaFluor Blue 610-70S dye shows much less cross-excitation and lower spectral spillover with the 561 nm yellow-green laser line, allowing detection of an additional marker labeled with, for example, NovaFluor Yellow 610 dye. The macromolecule-based NovaFluor Blue 610 dyes produce highly stable fluorescence, and stained samples retain their fluorescence intensity and spectral signature when stored at 4°C. Use NovaFluor dyes with CellBlox Plus Blocking Buffer to block non-specific binding of NovaFluor labels, PE and APC tandems observed with macrophages and monocytes.

Benefits of NovaFluor Blue 610-70S dye
  • Narrow emission spectrum and minimal cross-laser excitation for better resolution
  • Higher intensity allows it to be paired with medium-to-low abundance antigens
  • Can serve as a replacement for PE-tandem dyes using the blue laser, with reduced cross-laser excitation and fluorescent spillover
  • Single PE-tandems can be replaced by NovaFluor Blue 610-70S and NovaFluor Yellow 610 dyes to allow detection of an additional marker in a flow cytometry panel
  • NovaFluor Blue 610-30S and NovaFluor Blue 610-70S can be used together and unmixed using a spectral flow cytometer
  • Produces highly stable fluorescence and is compatible with all buffers tested
