β-Galactosidase, an important reporter gene marker encoded by lacZ, is commonly used for monitoring transfection efficiency in mammalian, yeast, and bacterial cells and identifying expression of recombinant fusion genes. E. coli β-galactosidase has a high turnover rate, hydrolyzing D-galactose from various β-galactosides, which allows for very low level detection in common cell types. β-Galactosidase substrates can also be used in conjunction with galactosidase-conjugated secondary detection agents in enzyme linked immunosorbent assays (ELISA) formats and in immunohistochemical techniques.
