Azo-Galactan from Potato by Molecular Depot is a dyed soluble azo-galactan from potato, a labelled substrate for galactan-degrading enzymes. The azo dye is attached covalently to the galactan, so enzymatic depolymerisation is read as the colour remaining in solution after the undigested polymer is precipitated with ethanol. It is used as a substrate in endo-galactanase assays, in pectic polysaccharide research and in plant cell wall enzyme characterisation. Each unit contains 1 g. MBP supplies Molecular Depot carbohydrate reagents to research labs in the United States, Canada and worldwide.
