Rabbit Anti-β-Galactosidase (E. coli)
Beta-galactosidase is coded by a gene (lac z) in the lac operon of Escherichia coli. It is a metalloenzyme that splits lactose into glucose and galactose. It hydrolyzes terminal, non-reducing beta-D-galactose residues in beta-D-galactosides.
Applications
Suitable for use in ELISA and Western Blot. Other applications not tested.
Recommended Dilution
ELISA: 1:5000-1:20,000 Western Blot: 1:1000-1:10,000 Optimal dilutions to be determined by the researcher.
