产品说明

一般描述

4′,5′-Dibromofluorescein (DBF) is a fluorone dye. Fluorone dyes are hydroxyl-xanthene dyes (homologues of fluorescein) and have been the most widely used class of organic fluorophores for labeling and sensing biomolecules. DBF is routinely used as a ligand for studying the properties of protein using spectral analysis.

应用

4′,5′-Dibromofluorescein has been used to stain proteins in 1-D and 2-D sodium dodecyl sulfatepolyacrylamide gel electrophoresis SDS-PAGE. This method is rapid, economical, and highly sensitive in comparison with other proteomic research staining methods.
