I'm never going to run these type of experiments but I do need to have a good idea of their timescale. After I fix my cells, if I stained my cells with histology stains like DAPI, Fluorescein, and ...
Is there a photobleaching-resistant, cell-permeant viability stain in the far red part of the spectrum?
I am looking for a live-cell–impermeable dye for viability. (The cells cannot be permeabilized and fixed in this experiment.) I would prefer with excitation and emission spectra similar to Cy5, but I ...
