Bulk inquiry 

Fluorescein (FAM) amine, isomerically pure dye (5-isomer). Unlike fluoresceinamine, this reagent contains a linker arm with an aliphatic amine group that is more reactive. It can react with electrophilic reagents like activated esters or epoxides, and be involved in enzymatic transamination.
