Product Description
Application
β-Galactosidase from bovine testes was used for coupling to Sepharose.
Biochem/physiol Actions
β-galactosidase cleaves lactose into its monosaccharide components, glucose and galactose. It also catalyses the transglycosylation of glucose into allolactose, the inducer of β-galactosidase, in a feedback loop.
Physical form
Suspension in 3.2 M (NH4)2SO4, pH approx. 5.0
Other Notes
One unit will hydrolyze 1.0 μmole of p-nitrophenyl β-
