β-D-galactosidase from E. coli

General description

Eukaryotic genes are usually cloned into E.coli β-galactosidase (lacZ) gene that results in a fusion hybrid of the desired gene product with the β-galactosidase enzyme . As the amount of the desired gene product in these cloned vector systems corresponds to the amount of β-galactosidase, enzyme assays for β-galactosidase can be utilized to detect the required gene product . Monoclonal anti-β-galactosidase antibodies are specific for β-galactosidase in E.coli and enable the analysis of β-galactosidase fusion proteins encoded by cloned vector systems.


Monoclonal anti-β-galactosidase antibodies may be used in dot blot (using soluble β-galactosidase), western blot (at a dilution of 1:1,000, using denatured-reduced Escherichia coli β-galactosidase) and immunocytochemistry. This antibody may also be used for immunochemical assays such as ELISA, immunoblot and immunohistochemistry by using the stepwise procedure or by the preparation of β-galactosidase anti-β galactosidase (BBAG) complex. Additionally, this product is suitable for the detection and purification of recombinant fusion proteins encoded by cloning vectors containing the β-galactosidase gene. Monoclonal anti-β-galactosidase antibody is also used for the immunoenzymatic staining of bone marrow and blood smears, and tissue sections.
