CPN™ 420 (Violet) has ex/em maxima of 390⁄420 which means it is compatible with instruments with 405, 375 or 355 nm laser excitation or standard filter sets such as those for DAPI.
CPN™ 420 (Violet) can be readily combined with additional CPNs to label multiple cellular proteins or biological sample components within the same mixture with minimal spectral overlap..
All CPNs™ come PEGylated as standard. CPNs™ are available with a number of surface chemistries including a carboxyl surface, maleimide and alkyne (click chemistry), to fit desired linkage preferences. CPNs™ are also available linked to streptavidin to bind biotinylated molecules.
