FDA；Fluorescein diacetate

CAS：596-09-8

C24H16O7=416.38

Grade：ACS

Content：≥97%

infrared spectrum：Consistent with structure

SD UVVI 1：488～494 nm（In 0.1@N@Sodium hydroxide）

Physicochemical properties : white or light yellow crystalline powder. Melting point 200-203 ℃, maximum absorption wavelength 498nm

Purpose: biochemical research. Esterase substrate for histochemical examination. Fluorescent matrix. Live cell staining is used for the study of intracellular interactions and membrane permeability. FDA can penetrate the cell membrane and store in living cells as fluorescein. Since the hydrophilicity of fluorescein is lower than that of BCECF or calcein, the amount of leakage of fluorescein from cells is also high. FDA can also be used for flow cytometry. The excitation and emission wavelengths of fluorescein were 488 nm and 530 nm, respectively.

Storage: - 20 ℃, protected from light
