Utilizing 4-nitrophenol (pNP)-glucopyranoside as a pseudosubstrate, 4-nitrophenyl α-D-galactopyranoside released a notably greater quantity of pNP at pH 4.0 in comparison to other pNP-glucopyranosides; however, no activity was found at pH 7.0. 1]. The yield of galactose residues released from 4-nitrophenyl α-D-galactopyranoside was mostly at pH 4.0, which is the pH level at which the yield threshold decreases the most, according to digestion experiments employing 4-nitrophenyl (pNP) as an artificial substrate [1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
