CPN™ 680 (Red)
CPN™ 680 (Red) has ex/em maxima of 400⁄680 which means it is compatible with instruments with 405 nm laser excitation or standard emission filters such as those for Texas Red/TRITC. CPN™ 680 (Red) can be readily combined with additional CPNs to label multiple cellular proteins in the same sample with minimal spectral overlap. CPN™ 680 (Red) absorbs in the blue with notable Stokes shift, larger than the majority of organic dyes.
CPNs™ are available with either a carboxyl surface or linked to streptavidin.
