Fluorescein di(β-D-galactopyranoside) 是 β-半乳糖苷酶的荧光底物 (λex=485 nm，λem=535 nm)。
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-D-galactopyranoside) method. Results show that the fluorescein produced by Fluorescein di(β-D-galactopyranoside) in Hs68 cells is proportional to the number of passages.
