Kanako Iha et al.
An enzyme immunoassay, in which an enzyme (e.g., alkaline phosphatase, ALP) is conjugated with an antibody, is a precise and simple protein detection method. Precise measurements of enzymes at low concentrations allow for ultrasensitive pro...
Simple Fluorescence Assay for Triethylamine Based on the Palladium Catalytic Dimerization of Benzofuran-2-boronic Acid [0.03%]
基于钯催化苯并呋喃-2-硼酸二聚化的一种简单的三乙胺荧光测定法
Akari Tange,Azumi Higashi,Naoya Kishikawa et al.
Akari Tange et al.
Although benzofuran-2-boronic acid hardly emits fluorescence, it can be rapidly converted to a highly fluorescent benzofuran dimer after mixing with a palladium catalyst and amine. We found that a fluorescence enhancement accompanying dimer...
