2,7-Dichlorodihydrofluorescein | 98.65% | 2,7-Dichlorodihydrofluorescein (DCFH2) is a non-fluorescent reactive oxygen species (ROS) probe with an excitation wavelength of 485-500 nm and an emission wavelength of 515-530 nm. 2,7-Dichlorodihydrofluorescein is first hydrolyzed by intracellular esterases and then oxidized by ROS to generate non-biomembrane-permeable, highly fluorescent 2,7-dichlorofluorescein (DCF). The fluorescence intensity of DCF is positively correlated with the ROS concentration. 2,7-Dichlorodihydrofluorescein can undergo oxidation reactions with a variety of ROS (such as ·OH, H2O2, ONOO-, etc.) and is used to quantitatively detect the level of oxidative stress inside and outside cells. It is suitable for oxidative stress analysis in in vitro cell models and in vivo targeted delivery (such as liver-targeted liposomes). | ||||||||||||||||||||

Erythrosine B (Standard) | ≥98% | Erythrosine B (Standard) (Erythrosin extra bluish (Standard); Tetraiodofluorescein disodium (Standard)) is the analytical standard of Erythrosine B (HY-D0259). This product is intended for research and analytical applications. Erythrosine B (Erythrosin extra bluish; Tetraiodofluorescein) is a visible red dye and insecticide with colorimetric and fluorescent properties. Erythrosine B serves as a membrane-impermeant live-cell dye for Gram-positive and Gram-negative bacteria, primarily staining dead cells with damaged plasma membranes. Erythrosine B exhibits photosensitive larvicidal toxicity against Culex pipiens quinquefasciatus larvae. Erythrosine B is used in live/dead bacterial assays in colorimetric and fluorescent measurements for low-, medium-, and high-throughput experiments, as well as in research related to mosquito-borne diseases and food coloring. | ||||||||||||||||||||
