Improved methods for detection of β-galactosidase (lacZ) activity in hard tissue [PDF]

open access: yes, 2012
The ß-galactosidase gene (lacZ) of Escherichia coli is widely used as a reporter gene. The expression of lacZ can be detected by enzyme-based histochemical staining using chromogenic substrates such as 5-bromo-4-chloro-3-indolyl-ß-D: -galactoside (X-gal).
