Chemical Properties
| Description | Fluorescein di(β-D-galactopyranoside) is a fluorogenic substrate for β-galactosidase (λem=535 nm, λex=485 nm). |
| In vitro | Fluorescein di(β-D-galactopyranoside) exhibits time- and dose-dependent increases in fluorescence in Hs68 cells, with fluorescence levels generated by the dual-substrate method significantly lower than those produced by Fluorescein di(β-D-galactopyranoside)[1]. |
| Cell Research | Procedure 1. After the cells have been cultured to the appropriate state, add 2 mM Fluorescein di-beta-D-galactopyranoside to each well after adding an aliquot of the reaction buffer and store the plate at 37°C in the dark for 24 hours without supply of CO2. 2. Observe and capture images using a fluorescence microscope. |

Calculator
In Vivo Formulation Calculator (Clear solution)
Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
For example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . A total of 10 animals were administered, and the formula you used is 5% 
DMSO+30% PEG300+5% Tween 80+60% Saline/PBS/ddH2O. So your working solution concentration is 2 mg/mL。Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSO (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
(mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.Preparation method for in vivo formula: Take 50 μL DMSO main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarify
main solution, add 300 μLPEG300 mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLSaline/PBS/ddH2O mix well and clarifyFor Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
