Fluorescein di(beta-D-galactopyranoside),

Fluorescein di(beta-D-galactopyranoside),

Application

Fluorescein di(?-D-galactopyranoside) (FDG) has been used for the detection of gene expression via FACS (fluorescence-activated cell sorting).

Fluorescein di(?-D-galactopyranoside) has been used as a substrate in ?-galactosidase assay.

Biochem/physiol Actions

Fluorescein di (?-D-galactopyranoside) (FDG) results in fluorescence after being hydrolyzed to fluorescein by ?-galactosidase. It gives fluorescence proportional to the enzymatic activity. This molecule is mainly required for the detection of gene expression in transfected cells when using ?-galactosidase (Lac Z) as a reporter gene.

Packaging
