About TCF4
This gene encodes transcription factor 4, a basic helix-loop-helix transcription factor. The encoded protein recognizes an Ephrussi-box ('E-box') binding site ('CANNTG') - a motif first identified in immunoglobulin enhancers. This gene is broadly expressed, and may play an important role in nervous system development. Defects in this gene are a cause of Pitt-Hopkins syndrome. In addition, an intronic CTG repeat normally numbering 10-37 repeat units can expand to >50 repeat units and cause Fuchs endothelial corneal dystrophy. Multiple alternatively spliced transcript variants that encode different proteins have been described. [provided by RefSeq, Jul 2016]

About CF680R
CF®680R from Biotium is a fluorophore with an excitation peak at 680 nm and an emission peak at 701 nm. It can be useful in both fluorescence microscopy and flow cytometry. For microscopy, CF®680R has been specifically validated in super-resolution imaging by STORM, STED and 2-Photon microscopy. It is spectrally similar to Alexa Fluor™ 680, IRDye® 680 and Cy5.5.
