X-Gal Powder

Chromogenic substrate for B-glactosidase. Cells with active B-galactosidase will produce a blue precipitate upon hydrolysis. It is the substrate of choice for blue-white selection of recombinant bacterial colonies. The X-gal quality and purity is essential to obtain high-quality reliable results, therefore our ultra pure molecular grade X-gal is optimized for use from the best raw materials.
