FITC (fluorescein isothiocyanate) is a commonly used fluorescent label for proteins, as it contains the groups required for conjugating to amino, sulfhydryl, imidazoyl, tyrosyl or carbonyl groups of proteins. FITC has a molecular weight of 389, and excitation and emission wavelengths of 494nm and 520nm, respectively, therefore emitting green visible light. This kit utilizes SpinOUT™ desalting columns, for the rapid removal of unconjugated dye.
The FITC labeling reagent is also available in our single use OneQuant™ format.
This kit is an improvement on Cat. # 786-059 as it offers greater free dye removal and complete coupling in less time.
