Description: 5-FAM (5-Carboxyfluorescein) (5-Carboxyfluorescein) contains a carboxylic acid, which can be used to react with primary amines via carbodiimide activation of the carboxylic acid. Fluorescein is the most common fluorescent derivatization reagent for labeling biomolecules. In addition to its excellent...

5-FAM is the purified single isomer of carboxyfluorescein. It is one of the most popular green fluorescent reagents used for labeling peptides, proteins and nucleotides.

Yellow-orange solid. Soluble in water, DMSO or DMF. The amine-reactive fluorescein derivatives are probably the most common fluorescent derivatization reagents for covalently labeling proteins. Carboxyfluorescein is better retained in cells than is fluorescein, its pKa of ~6.5 is lower than the cytosolic pH of most...

5-Carboxyfluorescein is a single isomer derivative of 5(6)-carboxyfluorescein (Cay-17172) that can be used to fluorescently label biomolecules through the interaction of carboxylic acid with primary amines. It demonstrates excitation/emission maxima of 492 and 518 nm, respectively.Formal Name:...

Amino acids are the basic units of proteins, which are linked by peptide bonds to form polypeptide chains that fold into proteins with specific functions. There are 20 common standard amino acids in nature, primarily distinguished by their side chains (R-groups). These differences give amino acids different...
