However, bioreporters are not widely used in field studies. Many of the bioreporter field protocols are suitable for liquid samples or include pipetting steps, which is a demanding task outside the laboratory. We present a bioreporter protocol without pipetting or sample type requirements. The protocol utilizes polyester swabs, commonly used in cleanroom technology. As an example contaminant, we used tetracycline and generated test samples with known concentrations up to the maximum tetracycline residue limit of milk set by the European Union (EU) regulation. The matrices of the test samples were Milli\u2010Q water, milk and soil. The swabs were first dipped in the bioreporter cell cultures and then to test samples and luminescence was measured after incubation. The standard deviation of measurements from ten replicate swabs was in the same range as commonly in pipetting protocols (4\u201319%). The test samples with lowest tetracycline concentration (5\u00a0ng mL<jats:sup>\u22121<\/jats:sup>) were distinguished from the control samples (0\u00a0ng mL<jats:sup>\u22121<\/jats:sup> tetracycline). Our results show that swabs can be used together with luminescent whole cell bioreporters, making it possible to conduct the measurements in field conditions.<\/jats:p>","DOI":"10.1002\/bio.3602","type":"journal-article","created":{"date-parts":[[2019,2,3]],"date-time":"2019-02-03T20:00:33Z","timestamp":1549224033000},"page":"249-254","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Field\u2010compatible protocol for detecting tetracyclines with bioluminescent bioreporters without pipetting steps"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5095-9602","authenticated-orcid":false,"given":"Johanna","family":"Muurinen","sequence":"first","affiliation":[{"name":"Department of Microbiology University of Helsinki  Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Avinash","family":"Pasupulate","sequence":"additional","affiliation":[{"name":"Department of Microbiology University of Helsinki  Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juha","family":"Lappalainen","sequence":"additional","affiliation":[{"name":"Aboatox Ltd  Masku Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5981-7566","authenticated-orcid":false,"given":"Marko","family":"Virta","sequence":"additional","affiliation":[{"name":"Department of Microbiology University of Helsinki  Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2019,2,3]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nm1145"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1128\/MMBR.00016-10"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00002-11"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mib.2003.09.009"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0048-9697(02)00233-4"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.2134\/jeq2008.0128"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0065-2113(05)87001-4"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/es0003021"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.3109\/03009734.2014.896438"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.trac.2010.06.004"},{"key":"e_1_2_6_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.aca.2008.08.003"},{"key":"e_1_2_6_13_1","doi-asserted-by":"publisher","DOI":"10.1098\/rstb.2013.0571"},{"key":"e_1_2_6_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.envint.2017.12.036"},{"key":"e_1_2_6_15_1","doi-asserted-by":"publisher","DOI":"10.1021\/ac010550v"},{"key":"e_1_2_6_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/1472-6750-9-41"},{"key":"e_1_2_6_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.chemosphere.2006.01.026"},{"key":"e_1_2_6_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/tox.2540020307"},{"key":"e_1_2_6_19_1","first-page":"31","volume-title":"Whole Cell Sensing System II: Applications","author":"Hynninen A.","year":"2010"},{"issue":"4","key":"e_1_2_6_20_1","doi-asserted-by":"crossref","first-page":"360","DOI":"10.1007\/s002480000095","volume":"41","author":"Pet\u00e4nen T.","year":"2001","journal-title":"Microb.
