Hi!
Please, can anyone explain the mechanism whereby the reporter gene, lacZ, is used in staining a piece of tissue for subsequent visualization of the product of the gene it is connected to? (I know that in the blue/white screening, it cleaves beta-gal and produces blue color, but how about in tissue itself???)
Thank you so much.
