About GFAP
This gene encodes one of the major intermediate filament proteins of mature astrocytes. It is used as a marker to distinguish astrocytes from other glial cells during development. Mutations in this gene cause Alexander disease, a rare disorder of astrocytes in the central nervous system. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

About DyLight 633
DyLight™ 633 is a red-emitting fluroescent dye that can be excited by the 628 nm laser and collected using a 670/30 nm bandpass filter. DyLight™ 633 has an excitation peak of 638 nm and an emission peak of 658 nm, and is spectrally similar to Alexa Fluor™ 633. DyLight™ 633 is most commonly used in flow cytometery and fluorescence microscopy applications.
