4-甲基伞形酮基β-D-葡糖苷酸水合物(MUG)是一种常用于检测转化植物的化学品。在用转化植物中编码的葡萄糖醛酸酶（GUS）处理之前，MUG显示低水平的荧光。 可以通过转化植物的MUG荧光对其进行鉴定。 4-Methylumbelliferyl β-D-Glucuronide Hydrate(MUG) is a chemical commonly used for the detection of transformed plants. MUG shows low levels of fluorescence until treatment with glucuronidase (GUS) encoded in transformed plants. Transformed plants can be identified by their MUG fluorescence.
