Produktinformation

• Name: 4-Nitrophenyl 2,3,4,6-tetra-O-acetyl-a-D-galactopyranoside
• Marke: Biosynth
• Beschreibung: 4-Nitrophenyl 2,3,4,6-tetra-O-acetyl-a-D-galactopyranoside is a chemiluminescent substrate that is used as a fluorescence indicator for the detection of β-galactosidase activities. This substrate has been shown to be useful for the detection of β-galactosidase in various types of samples such as culture media, environmental testing and food testing. 4NPTAG can also be used to detect β-galactosidase activity using fluorogenic substrates or chromogenic substrates. The enzyme activity can be detected by measuring the change in absorbance at 410 nm and the increase in luminescence at 460 nm.
