Description and Uses
6-Carboxyfluorescein (6-FAM) is derivative of fluorescein giving stable derivative upon conjugation with biopolymers.It has been used to check the plasma membrane integrity in sperm cells. The single isomer, 6-FAM, contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. Commercially available FAM is a mixture of two isomers, 5-FAM and 6-FAM, and the correct name is 5(6)-carboxyfluorescein.
