文献和实验, transfect the DNA into mammalian cells, and then fix and stain a tissue with X-gal. The cells that turn blue must have the beta galactosidase enzyme, the product of the lac Z gene, which could only have been expressed from the donated promoter. Ergo
Materials Fixative 2% Paraformaldehyde (in PBS) Staining solution 5 mM potassium ferricyanide, 5 mM potassium ferrocyanide, 2 mM MgCI, 0.01% sodium deoxycholate 0.02% Nonidet P-40 (NP-40) in PBS. X-gal Stock 40 mg
Detection of -Galactosidase Activity: X-gal Staining
X-gal staining is a rapid and convenient histochemical technique used to detect reporter gene expression. A prerequisite is the creation or acquisition of transgenic reporter mouse lines, in which the bacterial LacZ gene has been knocked
