General description

Monoclonal Anti-b-Galactosidase (mouse IgG1 isotype) is derived from the hybridoma produced by the fusion of mouse myeloma cells and splenocytes from an immunized mouse. ß-Galactosidase enzyme is encoded by lacZ gene of E. coli.

Specificity

The antibody may be used for amplification in immunoenzymatic staining by preparing a β-galactosidase anti-β-galactosidase (BGABG) soluble complex. It is not recommended for immunoblotting; it does not recognize denatured or reduced β-galactosidase.

Immunogen

β-galactosidase from E. coli

Application

Monoclonal Anti-β-Galactosidase-Biotin Conjugate antibody produced in mouse may be used with ExtrAvidin-Peroxidase in the dot blot technique on native, purified, or crude β-galactosidase. The antibody was used to detect β-galactosidase by immunofluorescence in paraffin-embedded adult mouse kidney sections. It was used in ELISPOT assays at a dilution of 1:1000.

Biochem/physiol Actions

β-galactosidase enzyme is encoded by lacZ gene of E. coli; it acts on lactose and cleaves it to glucose and galactose. Monoclonal Anti-β-Galactosidase-Biotin Conjugate antibody binds with soluble enzyme even when bound to a surface without causing any loss of enzymatic activity. It is used as readout for promoter activity in lacZ transfected cells.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide.

Preparation Note

Prepared by conjugation with ε-aminocaproyl biotin.
