General description
5-Bromo-4-chloro-3-indolyl β -D-galactopyranoside, commonly known as X-Gal, is a histochemical substrate for β-galactosidase.
Application
X-Gal is a chromogenic substrate for β-galactosidase that produces a rich blue color that can easily be detected visually over background. X-Gal is the substrate of choice for blue-white selection of recombinant bacterial colonies with the lac+ genotype.
5-Bromo-4-chloro-3-indolyl β-D-galactopyranoside has been used in the preparation of X-Gal stock solution to add it in LB agar plates for blue-white screening of transformants.
Biochem/physiol Actions
X-gal is routinely used to detect transgene activity in situ.
Preparation Note
A stock solution (100 mg/ml) is prepared by dissolving X-Gal in dimethylformamide and should be stored at −20°C and protected from light. Sterilization is not required.
Contains 5 mg substrate per tablet

Ischemia-reperfusion (I/R) injury associated with living donor liver transplantation impairs liver graft regeneration. Mesenchymal stem cells (MSCs) are potential cell therapeutic targets for liver disease. In this study, we demonstrate the impact of MSCs against hepatic I/R injury and hepatectomy.
