Inquiry
Alfa Chemistry has always been committed to providing customers with the best quality service. With quantum dot fluorescent probes, the detection of ALP activity in human serum can be well completed. Alfa Chemistry's professional team strengthens cooperation to develop a series of high-quality solutions for customers.
Background
ALP is a hydrolytic enzyme with specificity for phosphate substrates, which can catalyze the hydrolysis or dephosphorylation of a variety of phosphorus-containing compounds in alkaline media. In biological analysis, ALP can be used as an enzyme label or indicator in a reaction to quantify the combined process of immunoassay and genetic testing or other methods. At present, the detection methods of ALP activity mainly include colorimetric method, fluorescence analysis method, electrochemical analysis method and surface enhanced Raman scattering method. Among them, the fluorescence analysis method has greater detection advantages due to its fast, simple and sensitive signal transduction ability. Copper-phenanthroline complex, polydopamine nanoparticles, cobalt hydroxide-copper nanoclusters, silver fluorescent probes such as nanoclusters, gold nanoparticles, molybdenum disulfide quantum dots and carbon quantum dots are widely used in the detection of ALP activity. Based on the properties of benzoquinones that can statically quench the fluorescence of GQDs, a GQDs fluorescent probe can be used to efficiently detect ALP activity.

Highly sensitive detection of ALP
Hydrogen peroxide (H2O2) is catalyzed by horseradish peroxidase (HRP) to produce hydroxyl groups, which can oxidize o-DHB to o-benzoquinone and quench GQDs fluorescence. Ascorbic acid 2-phosphoric acid (AAP) can be catalyzed by ALP to produce ascorbic acid (AA). AA with strong reducing ability can effectively remove H2O2 and hydroxyl in solution, and then inhibit the formation of o-quinone, inducing the fluorescence recovery of GQDs. As the activity of ALP increased, the fluorescence at 440 nm increased continuously, so a highly sensitive detection method for ALP was established.
