β-Galactosidase, E. coli  (Synonyms: EC 3.2.1.23; GAL)

Cat. No.: HY-P2869
COA Handling Instructions

β-Galactosidase (EC 3.2.1.23) is a glycoside hydrolase that hydrolyzes the β-glycosidic bonds formed between galactose and its organic moieties. In E.coli, the lacZ gene is the structural gene of β-galactosidase, which can be used as part of the induction system lac operon. β-Galactosidase can hydrolyze lactose to form glucose and galactose, and enter glycolysis; it can also catalyze the transgalactosylation of lactose into allolactose; allolactose can be cracked into monosaccharides.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
