설명

일반 설명

X-Gal is a chromogenic substrate for β-galactosidase that produces a rich blue color that can easily be detected visually over background. It is soluble in dimethylformamide and methanol. The product is not soluble in water.

애플리케이션

X-Gal has been used for immunohistocytochemistry applications. It is also the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac⁺ genotype.
