non-recombinants.
Applications
• Blue/white screening to differentiate recombinant (white) from non-recombinant (blue) colonies
• Colorimetric assay based on lacZ reporter gene expression in transfected eukaryotic cells
• Immunoblotting and immunocytochemical assays based on β-galactosidase activity
