BpNPG7 , 4-Nitrophenyl 4,6-benzylidene-a-D-maltoheptaoside

4-Nitrophenyl 4,6-benzylidene-α-D-maltoheptaoside is a high quality and highly purified chemical used in the diagnosis of carbohydrate fermentation. It is a chromogenic substrate that can be used to test for the presence of enzymes such as α-amylase, β-amylase, and α-glucosidase. It reacts with these enzymes to produce a color change from yellow to blue. 4-Nitrophenyl 4,6-benzylidene-α-D-maltoheptaoside is also a fluorogenic substrate that can be used to measure the activity of β-galactosidase.
