Thermo Fisher Scientific β-Gal Staining Kit

Invitrogen™ β-Gal Staining Kit

The β-Gal Staining Kit allows you to determine the percentage of transfected cells expressing lacZ.
lacZ is a bacterial gene often used as a reporter construct in eukaryotic transfection experiments.
The gene product of lacZ, β-galactosidase, is resistant to proteolysis in cellular lysates and its activity is easily assayed.
β-galactosidase catalyzes the hydrolysis of X-gal, producing a blue color that can be easily visualized under a microscope.
