| Questions And Answer | Back Directory | [Note]
Hans et al. report that 2',7'-Dichlorofluorescein (DCF) finds legitimate experimental use in the generation of standard curves used to calibrate DCFH2-DA experimental results, post-chromatography estimation of carbohydrates and in indirect fluorimetric detection in open tubular capillary chromatography (OTC-HPLC). However, DCF is inappropriate for demonstrating ROS as it is oxidized to a non-fluorescent compound in the presence of hydroxyl radicles[1].
