产品介绍

FDGlcU 荧光素二-β-D-葡糖醛酸是美国AAT Bioquest生产的用于检测FDGlcU的试剂，来自于大肠杆菌的β-葡萄糖苷酸酶（GUS），被用于转基因植物中具有优良特性的标志基因。GUS报告基因系统具有很多优势，如稳定表达的大肠杆菌的GUS酶对正常植物代谢无干扰，而高等植物中具有低背景的GUS活性。FDGlcU被认为是测定GUS酶最敏感的荧光底物之一。无色且非荧光的FDGlcU 被水解成高荧光的荧光素，它可以展现出完美的光谱特性（Ex/Em=492/520nm），与大多数荧光检测设备的最佳检测窗口所匹配。葡萄糖苷酸酶催化水解FDGlcU ，并在520nm处产生荧光。此外，由于FDGlcU的产物，荧光素具有强大的消光系数（100,000 cm-1mol-1），FDGlcU也被作为显色底物用于在发光模式下检测葡萄糖苷酸酶的活性。通过荧光显微镜或者流式细胞仪FDGlcU也能用来识别GUS阳性表达细胞。金畔生物是AAT Bioquest的中国代理商，为您提供最优质的FDGlcU 荧光素二-β-D-葡糖醛酸。
