4-Nitrophenyl-α-D-maltohexaoside

4-Nitrophenyl-α-D-maltohexaoside by Molecular Depot is a 4-nitrophenyl-α-D-maltohexaoside, a chromogenic substrate for α-amylase that gives a yellow product. A six-glucose chain is long enough to fill the extended binding cleft of an α-amylase, which an enzyme that acts on short substrates cannot use, so the substrate reports amylase activity specifically. It is used as a substrate in colorimetric α-amylase assays, in clinical chemistry amylase method development and in carbohydrase activity screening. Each unit contains 50 mg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
