Helix NP NIR 1 mL

Helix NP™ NIR is a far-red emitting nucleic acid stain. It is impermeant to live cells and thus can be used for the discrimination of live and dead cells. In immunofluorescence microscopy, it can be used as a nuclear counterstain in cells and tissue. It is optimally excited at 640 nm with an emission at 660 nm, which can be detected in the Alexa Fluor® 647 or APC channel.;
