MB 680R is a bright and photostable near-infrared dye that fluoresces around 700 nm in the borderline spectral region between the far and near-infrared. MB 680R dye is water soluble and pH insensitive in the pH 4 to pH 10 range. MB 660R is a rhodamine-based dye that, like normal rhodamine dyes, is very bright and very lightfast. The exceptional photostability and excellent brightness of MB 680R make this dye ideal for confocal microscopy, single-molecule imaging, and other applications where brightness and photostability are required.
