Chemical Property/Description:

 

Fluorescein disodium salt is a orange red powder, soluble in water and alcohol solvents, slightly soluble in ether. It is yellow under acidic conditions and green fluorescent under alkaline conditions. Its melting point is about 320 ° C.

 
Main Uses:

 


Fluorescein disodium salt has been widely used in chemical analysis, biomedicine, fluorescence microscopy and chemiluminescence. It is usually used as a biochemical reagent in experiments to determine enzyme activity, protein content and cell activity. Sodium fluorescein can also be used to prepare other fluorescent dyes, such as fluorescein phosphate.
 

Fluorescein disodium salt can also be used in cell biology research and molecular biology research. Researchers typically use sodium fluorescein as a substrate to detect the expression and localization of proteins or other biomolecules. This approach could help scientists better understand the fundamental processes of life and provide a basis for developing new treatments.
