≥8.0 units/mg solid

Synonym: β-D-Galactoside galactohydrolase, Lactase from Aspergillus oryzae

Purchase

Description

Packaging

25000, 125000, 500000 units in poly bottle

Unit Definition

One unit will hydrolyze 1.0 μmole of lactose per minute at pH at 4.5 at 30 °C.

Application

β-Galactosidase was used for reversed-phase (RP) adsorption. It was also used in the hydrolysis of whey lactose.

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.
