Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, and liver blood flow, and for ophthalmic angiography. ICG binds tightly to plasma proteins and becomes confined to the vascular system. Indocyanine Green is a…

Lucifer Yellow CH is the hydrazine (-NH-CO-NH-NH2) form of the dye compared to Lucifer Yellow VS, which is the vinyl sulfone (-Ph-SO2-CH=CH2) form. It is a highly fluorescent dye useful in marking nerve cells. Lucifer yellow CH has been used to demonstrate electrical coupling between hamster…

Fluorescamine is a non-fluorescent reagent that reacts readily with primary amino groups in amino acids and peptides to form highly fluorescent derivatives, whereas the reagent and its degradation products are non-fluorescent. No significant fluorescence with ammonia. Low background due to…
