4-MU-BETA-D-LACTOSIDE - Introduction

It is a compound that contains an umbelliferyl group and a lactopyranoside group in its chemical structure.

Greenish-yellow fluorescence in aqueous solution, which can be used to detect and analyze enzyme activity. It is a substrate particularly suitable for detecting the activity of the enzyme β-galactosidase. When the activity of the enzyme is present, it is hydrolyzed by the enzyme and a fluorescent signal is generated, which is used to measure the activity and concentration of the enzyme. This method is widely used in biochemical and biological research.
The preparation method of
is generally obtained by chemical synthesis. The specific preparation step may include reacting 4-methylumbelliferal with β-D-lactopyranoside to synthesize the target compound under suitable conditions.

With regard to safety information, toxicity and safety have not been adequately studied because their uses are mainly in the laboratory and research areas. However, in general, operators should take appropriate protective measures for any chemical substance, including wearing protective glasses, gloves and laboratory clothing. At the same time in the process of operation to avoid contact with skin and food, to ensure that the experimental site is well ventilated. When using this compound, the relevant safety guidelines should be followed, and the risks should be assessed and appropriate protective measures should be taken on a case-by-case basis.
