MB 633 NHS Ester is a novel rhodamine dye with an absorption peak at 630 nm. The most important advantage of the MB 633 NHS Ester is its photostability, which can be optimally excited by a 633 nm He-Ne laser or a 635 nm red diode laser with a maximum emission wavelength of 650 nm. MB 633 and other rhodamine-based far-red MB dyes. The combination of superior brightness and photostability makes far-red MB dyes ideal for detection in the long wavelength region on a variety of instruments.
