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 DyLight 488
DyLight™ 488 has an excitation peak at 493 nm and an emission peak at 518 nm and is spectrally similar to Alexa Fluor™ 488, fluorescein and FITC. DyLight™ 488 is most commonly used in flow cytometery, and fluorescence microscopy applications.
