X-gluc (CHX salt) by Molecular Depot is a X-gluc as the cyclohexylammonium salt, a chromogenic β-glucuronidase substrate that yields a blue precipitate. The GUS reporter system relies on plants having essentially no endogenous β-glucuronidase, so the bacterial enzyme introduced as a reporter produces a signal against no background at all. It is used in GUS reporter gene staining of plant tissue, in colony and transformant screening and in β-glucuronidase histochemistry. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
