5-bromo-3-indoxyl Nonanoate by Molecular Depot is a 5-bromo-3-indoxyl nonanoate, a chromogenic substrate for lipase and esterase activity. The released indoxyl oxidises and dimerises in air to an insoluble indigo dye, so the colour forms as a precipitate where the enzyme is, and the nine-carbon acyl chain selects for the enzymes that prefer longer substrates. It is used to detect lipase and esterase activity on agar plates and in gels, in microbial identification media and in histochemical staining. Each unit contains 100 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
