fluorescein di(beta-D-galactopyranoside)

Description:
Fluorescein di(beta-D-galactopyranoside) is a fluorescent compound commonly used in biochemical assays and research, particularly for studying enzyme activity and cellular processes. It is a glycoside derivative of fluorescein, which imparts its characteristic bright green fluorescence when excited by light. The compound consists of a fluorescein moiety linked to two beta-D-galactopyranoside units, making it a substrate for galactosidase enzymes. Upon enzymatic cleavage, fluorescein is released, resulting in an increase in fluorescence intensity, which can be quantitatively measured. This property makes it a valuable tool in various applications, including cell biology, microbiology, and drug discovery. The compound is typically soluble in water and organic solvents, and its stability can be influenced by pH and temperature. Safety precautions should be taken when handling this substance, as with any chemical, to avoid potential hazards. Overall, fluorescein di(beta-D-galactopyranoside) serves as an important reagent in the study of glycosidase activity and cellular uptake mechanisms.
