However, the detection equipment is often expensive, fragile, and hard to deploy widely. Quantum dots (Qdot) are nanocrystals made of semiconductor materials that emit light at different wavelengths according to the size of the crystal, with increased brightness and stability. Here, we have evaluated a small benchtop \u201cpersonal\u201d optical imager (ArrayCAM) developed for quantification of protein arrays probed by Qdot\u2010based indirect immunofluorescence. The aim was to determine if the Qdot imager system provides equivalent data to the conventional organic dye\u2010labeled antibody\/laser scanner system. To do this, duplicate proteome microarrays of Vaccinia virus,\n                    <jats:italic>Brucella melitensis<\/jats:italic>\n                    and\n                    <jats:italic>Plasmodium falciparum<\/jats:italic>\n                    were probed with identical samples of immune sera, and IgG, IgA, and IgM profiles visualized using biotinylated secondary antibodies followed by a tertiary reagent of streptavidin coupled to either P3 (an organic cyanine dye typically used for microarrays) or Q800 (Qdot). The data show excellent correlation for all samples tested (\n                    <jats:italic>R<\/jats:italic>\n                    &gt; 0.8) with no significant change of antibody reactivity profiles. We conclude that Qdot detection provides data equivalent to that obtained using conventional organic dye detection. The portable imager offers an economical, more robust, and deployable alternative to conventional laser array scanners.\n                  <\/jats:p>","DOI":"10.1002\/pmic.201500375","type":"journal-article","created":{"date-parts":[[2016,2,4]],"date-time":"2016-02-04T04:54:08Z","timestamp":1454561648000},"page":"1271-1279","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Evaluation of quantum dot immunofluorescence and a digital CMOS imaging system as an alternative to conventional organic fluorescence dyes and laser scanning for quantifying protein microarrays"],"prefix":"10.1002","volume":"16","author":[{"given":"Aarti","family":"Jain","sequence":"first","affiliation":[{"name":"Division of Infectious Diseases Department of Medicine University of California Irvine  Irvine CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omid","family":"Taghavian","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases Department of Medicine University of California Irvine  Irvine CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derek","family":"Vallejo","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering University of California Irvine  Irvine CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Emmanuel","family":"Dotsey","sequence":"additional","affiliation":[{"name":"Division of Infectious Diseases Department of Medicine University of California Irvine  Irvine CA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Grace Bio\u2010Labs, Inc  Bend OR USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian G.","family":"Bell","sequence":"additional","affiliation":[{"name":"Grace Bio\u2010Labs, Inc  Bend OR USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad","family":"Greef","sequence":"additional","affiliation":[{"name":"Grace Bio\u2010Labs, Inc  Bend OR USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
