Abstract:

As an important part in "bottom-up" strategy of proteomics, immobilized enzyme reactors have great significance in the development of fast and more efficient protein analytical method, owing to its advantages of high speed and enzymatic efficiency, good stability and activity, easy operation, and the possibility of hyphenating with multiple detection instruments. In this paper, the preparation methods of immobilized enzyme reactors and their applications in proteomic investigation are introduced, focusing on the nature of enzymes, the immobilization methods and the carrier materials used for immobilizing enzyme. In recent years, the investigations are focused on increasing the immobilization amounts of enzyme, keeping enzymatic activity, improving enzymatic efficiency and decreasing nonspecific adsorption. The investigation results showed that by using novel carriers such as nanomaterial and monolith, increasing of hydrophilicity of carrier and tandem hydrolysis with multiple enzymes can greatly improve the performance of immobilized enzyme reactors and increase protein identification efficiencies.
