5-Carboxyfluorescein Usage And Synthesis
  • Description5-Carboxyfluorescein is a single isomer derivative of 5(6)-carboxyfluorescein (Item No. 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.
  • Chemical PropertiesOrange Solid
  • UsesA useful reagent for the preparation of hydrolytically stable fluorescent conjugates and is a useful starting material for the synthesis of other fluorescein-derives reagent
  • UsesDerivative of fluorescein giving stable derivative upon conjugation with biopolymers.
