6,8-Difluoro-4-methylumbelliferyl b-D-galactopyranoside

6,8-Difluoro-4-methylumbelliferyl b-D-galactopyranoside (6FAMB) is a fluorescent dye that can be used as a marker for antibody binding. It binds to the Fc region of antibodies and stains erythrocytes. 6FAMB has been used to study the activity of antimicrobial peptides in human serum. The fluorescence intensity of 6FAMB increases when it is incubated with cells, which may be due to its protease activity. The enzyme activity can be inhibited by phosphatase inhibitors such as sodium fluoride and sodium orthovanadate. 6FAMB can also be used for diagnostic purposes in assays.
