General description

β-Galactosidase is coded by the LacZ gene which helps to transform lactose into galactose.
β-galactosidase is a ~465 kDa tetrameric protein. 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.

Specificity

The antibody may be used for detection of β-galactosidase expressed by the E. coli lacZ gene encoded in many cloned gene sequences; serves as an indicator for fusion proteins encoded by an inserted DNA sequence.

Immunogen

β-D-galactosidase from E. coli

Application

Monoclonal Anti-β-Galactosidase antibody produced in mouse has been used for western blotting.
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.

Biochem/physiol Actions

β-galactosidase catalyses the hydrolysis of lactose to form glucose and galactose. It serves as a reporter enzyme in a number of analysis such as studying the regulation of gene expression, protein function and structure determination, and examining of target gene expression. β-galactosidase is also known to yield coloured products by acting on several substrates. Thus, it is prefered as a reporter enzyme in applications involving gene expression regulation, analysis of protein function/structure, and target gene expression.

Disruption of epithelial integrity contributes to chronic inflammatory disorders through persistent activation of stress signalling. Here we uncover a mechanism whereby disruption of apico-basal polarity promotes stress signalling. We show that depletion of Scribbled (Scrib), a baso-lateral determinant, causes epithelial

A panel of seven mouse monoclonal antibodies (BG-01-BG-07) was prepared against beta-galactosidase derived from E. coli. The antibodies are beta-galactosidase specific, show no cross-reactivity with other E. coli proteins and can be used for identification and characterization of beta-galactosidase fusion
