The column was prepared by coupling of 3-aminophenylboronic acid on the glass beads through a \u03b3-glycidoxypropyltrimethoxysilane (GPMS) linkage. Based on an indirect competitive immunoreaction, the mixture of CEA sample and enzyme conjugated CEA antibody (HRP-anti-CEA) was incubated in advance, followed by direct injection to the column to capture free HRP-labeled CEA antibody in the column. The trapped HRP-labeled antibody was detected by flow inject chemiluminescence in the presence of luminol and hydrogen peroxide. The decreased chemiluminescent signal was proportional to the concentration of CEA in the range of 3.0\u201330.0 ng\/mL with a correlation coefficient of 0.998. The column showed an acceptable reproducibility and stability and is potentially used for practical clinical detection of the serum CEA level.<\/jats:p>","DOI":"10.3390\/s91210389","type":"journal-article","created":{"date-parts":[[2009,12,22]],"date-time":"2009-12-22T10:56:36Z","timestamp":1261479396000},"page":"10389-10399","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Flow Injection Chemiluminescent Immunoassay for Carcinoembryonic Antigen Using Boronic Immunoaffinity Column"],"prefix":"10.3390","volume":"9","author":[{"given":"Xiaoling","family":"Ma","sequence":"first","affiliation":[{"name":"Nanjing Maternity and Child Health Care Hospital, Nanjing Medical University, Nanjing, 210004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Huihui","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Biofunctional Materials, College of Chemistry and Environmental Science, Nanjing Normal University, Nanjing, 210097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min","family":"Wu","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Biofunctional Materials, College of Chemistry and Environmental Science, Nanjing Normal University, Nanjing, 210097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chong","family":"Sun","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Biofunctional Materials, College of Chemistry and Environmental Science, Nanjing Normal University, Nanjing, 210097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laifa","family":"Li","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Biofunctional Materials, College of Chemistry and Environmental Science, Nanjing Normal University, Nanjing, 210097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaodi","family":"Yang","sequence":"additional","affiliation":[{"name":"Jiangsu Key Laboratory of Biofunctional Materials, College of Chemistry and Environmental Science, Nanjing Normal University, Nanjing, 210097, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,12,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1007\/BF00469226","article-title":"Carcinoembryonic antigen: molecular cloning and expression of CEA-related antigens, and the use of monoclonal antibodies to CEA in tumor imaging and therapy","volume":"330","author":"Shively","year":"1988","journal-title":"Fresenius' J.
