beta-Galactosidase substrates

The Lac Z gene encoding the enzyme beta-galactosidase is used widely as a reporter gene in bacteria, yeast, and animal experimental models. Because the enzyme is highly specific and stable, avidin and antibody beta-galaxtosidase conjugates are useful detection reagents for ELISA applications. Biotium offers a series of chromogenic beta-galactosidase substrates that produce highly colored precipitates. In addition, we offer the fluorogenic beta-galactosidase substrate FDG.
