  • RelevanceBeta 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. Activation by cations seems to be substrate dependent. K+, Na+, NH4+, Rb+, Cs+ and Mn++ all activate enzyme activity based upon the substrate used.

    I would recommend ab6645. We do not know if this antibody has been used in formalin treated tissue, however it has been used with IHC and I would expect it to work with formalin treated tissue as it is a polyclonal and thus recognises multiple epitopes.

    This antibody has not yet been tested in Flow Cytometry, therefore we can't guarantee that it will work. For a protocol regarding the staining of red blood cells, please see the general FACS protocol on the Abcam website

    This antibody is biotinylated so there will be no need for a secondary antibody. You only require an ABC kit and chromogen. I recommend ab8621 for the ABC kit (Super ABC / Horseradish Peroxidase Basic Kit) and ab8184 (HRP Chromogen kit (DAB)) for the ...
