CE-ECL is a combination of capillary electrophoresis(CE) and electrochemiluminescence(ECL), which has the advantages of high separation efficiency and high detection sensitivity. This article applied CE-ECL to study the interactions of protein and drug and enzyme reactions. The main research work was summarized as follows:Chapter one: It Outlined the capillary electrophoresis(CE)-electrochemiluminescence(ECL) technology and its application in pharmaceutical analysis, drug and protein analysis, enzyme activi...
