PFB-FDGlu is a cell membrane-permeable fluorescent substrate specifically used for detecting glucocerebrosidase (GCase) activity in living cells. After being cleaved by lysosomal GCase, PFB-FDGlu releases a green fluorescent product, enabling quantitative analysis of individual cell enzyme activity through flow cytometry, fluorescence microscopy, or high-content imaging techniques[1].

PFB-FDGlu是一种具有细胞膜渗透性的荧光底物,可特异性用于活细胞中葡糖脑苷脂酶(GCase)活性的检测。PFB-FDGlu能够在被溶酶体内的GCase切割后释放绿色荧光产物,从而通过流式细胞术、荧光显微镜或高内涵成像技术实现对单个细胞酶活性的定量分析[1]。
