| | Carboxyfluorescein Usage And Synthesis |
| Description | Carboxyfluorescein is a derivatives of fluorescein. lt iscommonly used to label biomolecules through a reaction involving the carboxyl group. Unlike itssuccinimidyl ester derivative CFSE, Carboxyfluorescein is membrane impermeant.As a result,it can be used in studies of membrane permeability. Carboxyfluorescein displaysexcellent fluorescence ,and its excitation maximumclosely matches the 488 nm spectral line of argon-ion lasers. | | Uses | Carboxyfluorescein is used to characterize tumor cells and normal cells in vivo. It labels proteins derived through N-hydroxysuccinimide (NHS) ester-mediated derivatization. Carboxyfluorescein is suitable for detecting cell viability while developing an in vitro anthelmintic drug assay. |
