CellBrite Blue

CellBrite Blue (Ex-Max 366 nm/Em-Max 441 nm)

Biotium’s CellBrite® Cytoplasmic Membrane Dyes are ready-to-use dye stock solutions that can be added directly to normal culture media to uniformly label live cell membranes with lipophilic carbocyanine and NIR dyes that emit across a wide range of emission peaks. These dyes will not be retained with fixation and permeabilization and are used for cellular morphology and membrane staining.
