설명

일반 설명

5(6)-Carboxyfluorescein, also known as 5(6)-FAM, is a fluorescent tracer and available as a mixture of 5-Carboxyfluorescein and 6-Carboxyfluorescein isomers. The fluorescence of 5(6)-Carboxyfluorescein is determined by the xanthene moiety. 5(6)-Carboxyfluorescein has two characteristic properties:

• It has 2 wavelengths for maximum absorbance (465 and 490nm).
• And its fluorescence emission, at 515nm(max.), increases as a function of pH in the physiological range of 6-7.4.

애플리케이션

5(6)-Carboxyfluorescein is used to characterize tumor cells and normal cells in vivo. It labels proteins derived through N-hydroxysuccinimide (NHS) ester-mediated derivatization. 5(6)-Carboxyfluorescein is suitable for detecting cell viability while developing an in vitro anthelmintic drug assay.
