产品详情	Fluorescein di(β-D-galactopyranoside) 是 β-半乳糖苷酶的荧光底物 (λ_ex=485 nm，λ_em=535 nm)。
生物活性	Fluorescein di(β-D-galactopyranoside) is a fluorogenic substrate for β-galactosidase (λ ex =485 nm, λ em =535 nm).
性状	Solid
体外研究(In Vitro)	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. has not independently confirmed the accuracy of these methods. They are for reference only.

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
