However, the implementation of screening in clinical practice is hindered by the slow turnaround time and high cost of conventional HLA genotyping methods. We have developed a biosensor platform using interdigitated electrode (IDE) functionalized with a monoclonal antibody to detect cells expressing HLA-B*57:01. This platform was evaluated using cell lines and peripheral blood mononuclear cells expressing different HLA-B alleles. The functionalized IDE sensor was able to specifically capture HLA-B*57:01 cells, resulting in a significant change in the impedance magnitude in 20 min. This IDE platform has the potential to be further developed to enable point-of-care HLA-B*57:01 screening.<\/jats:p>","DOI":"10.3390\/s19163543","type":"journal-article","created":{"date-parts":[[2019,8,15]],"date-time":"2019-08-15T04:22:54Z","timestamp":1565842974000},"page":"3543","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Rapid Detection of HLA-B*57:01-Expressing Cells Using a Label-Free Interdigitated Electrode Biosensor Platform for Prevention of Abacavir Hypersensitivity in HIV Treatment"],"prefix":"10.3390","volume":"19","author":[{"given":"Jianxiong","family":"Chan","sequence":"first","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gita V.","family":"Soraya","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"},{"name":"Department of Biochemistry, Faculty of Medicine, Hasanuddin University, Makassar 90245, Indonesia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lauren","family":"Craig","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1295-8796","authenticated-orcid":false,"given":"Shah M.","family":"Uddin","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marian","family":"Todaro","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"},{"name":"Department of Neurology, Royal Melbourne Hospital, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Duc H.","family":"Huynh","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Melbourne School of Engineering, The University of Melbourne, Victoria 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chathurika D.","family":"Abeyrathne","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Melbourne School of Engineering, The University of Melbourne, Victoria 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lyudmila","family":"Kostenko","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, The Peter Doherty Institute for Infection and Immunity, The University of Melbourne, Victoria 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James","family":"McCluskey","sequence":"additional","affiliation":[{"name":"Department of Microbiology and Immunology, The Peter Doherty Institute for Infection and Immunity, The University of Melbourne, Victoria 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Efstratios","family":"Skafidas","sequence":"additional","affiliation":[{"name":"Department of Electrical and Electronic Engineering, Melbourne School of Engineering, The University of Melbourne, Victoria 3010, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick","family":"Kwan","sequence":"additional","affiliation":[{"name":"Department of Medicine, Royal Melbourne Hospital, The University of Melbourne, Victoria 3050, Australia"},{"name":"Department of Neurology, Royal Melbourne Hospital, Victoria 3050, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,14]]},"reference":[{"key":"ref_1","unstructured":"Kass-Bartelmes, B.L.
