Abstract
The detection of CD59 is of great clinical importance since it is an important glycoprotein that can serve as a biomarker related to kinds of cancers. In this work, we prepared host-guest interaction based oriented epitope molecularly imprinted polymer (hg-EMIP) for the immobilization of CD59 N-terminal epitopes. Cucurbit[7]uril (CB[7]) and l-phenylalanine (L-phe) were employed as the host and guest; and tannic acid (TA) with abundant hydroxyl groups and diethylenetriamine (DETA) were chosen as the functional monomer and crosslinking agent, respectively. The obtained hg-EMIP can specifically recognize CD59 with the adsorption capacity of 88.2 mg/g and imprinting factor of 5.63, and possesses high reusability. The hg-EMIP-based method possesses a wide linear range (1 ng/mL - 1 μg/mL) and low limit of detection (0.44 ng/mL), and can be successfully used for the detection of CD59 in human serum sample. This study provides a scheme for the preparation of host-guest based epitope molecularly imprinted polymers for helping to identify potential disease biomarkers efficiently.
期刊介绍:
The Journal of Chromatography A provides a forum for the publication of original research and critical reviews on all aspects of fundamental and applied separation science. The scope of the journal includes chromatography and related techniques, electromigration techniques (e.g. electrophoresis, electrochromatography), hyphenated and other multi-dimensional techniques, sample preparation, and detection methods such as mass spectrometry. Contributions consist mainly of research papers dealing with the theory of separation methods, instrumental developments and analytical and preparative applications of general interest.
