Substrates and Kits

Marker Gene provides various β-glucuronic acid substrates for detection of GUS expression, all of which contain the sugar D-glucopyranosiduronic acid attached by glycosidic linkage to a hydroxyl group of a chromogenic, fluorogenic, or other detectable molecule. This includes the most widely used fluorogenic substrate for detection of β-glucuronidase activity in vitro: 4-methylumbelliferyl β-D-glucuronide (4-MUG). Our best in class and diverse selection of reporter gene substrates are essential tools for any plant lab interested measuring activity in plant lysates, homogenates, leaf disks or whole plant assays.
