生物活性

产品描述	Fluorescein di(β-D-galactopyranoside) 是 β-半乳糖苷酶的荧光底物 (λex=485nm，λem=535nm)。
靶点
体外研究	The fluorescence produced by Fluorescein di(β-D-galactopyranoside) increases in a time- and dose-dependent manner. The level of fluorescence produced by the double-substrate method is much lower than that by the Fluorescein di(β-Dgalactopyranoside) method. Results show that the fluorescein produced by Fluorescein di(β-D-galactopyranoside) in Hs68 cells is proportional to the number of passages

推荐实验方法(仅供参考)

Cell Assay

The cells (5×10³ cells per well) are cultured in a 96-well plate overnight for attachment, washed, and then fixed in solutions. An aliquot (100μL) of the reaction buffer (i.e., the staining solution without X-Gal) is added into each well. Then, 10μL of 2mM Fluorescein di(β-D-galactopyranoside) is added per well and the plate is incubated in the dark at 37°C for 24 h without CO2 supply. After incubation at 37°C for 24 h, 100μL of the supernatant is transferred to a 96-well plate for fluorescent measurement in triplicates. The fluorescein fluorescence is measured using a fluorometer with an excitation at 485nm and an emission at 535nm
