IPEC-1 cells grown on Thincert™ wells were washed once with PBS, and 125 μl of the labeled bacterial suspensions in DMEM/Ham’s F-12 [1:1] medium at A600nm values of 0.25, 0.5 or 1 were added per well. The plates were incubated for one hour at +37°C, 5% CO2 followed by five washes with PBS. The cells were lysed by adding 250 μl of 1% SDS in 0.1 M NaOH per well and by incubating overnight at +37°C, and the radioactivity of the lysed samples (output) was measured by liquid scintillation counting. The input radioactivity values were determined by liquid scintillation counting of the cell suspensions in DMEM/Ham’s F-12 [1:1] (A600nm = 0.25, 0.5 or 1), first treated with an equal volume of 1% SDS in 0.1 M NaOH overnight at +37°C. The adherence was expressed as the proportion (%) of the original radioactivity remaining, after first subtracting the background radioactivity from IPEC-1 cells incubated without bacteria (for outputs) and from DMEM/Ham’s F-12 [1:1] medium (for inputs).","divisions":[{"label":"Title","span":{"begin":0,"end":50}}],"tracks":[{"project":"MicrobeTaxon","denotations":[{"id":"T91","span":{"begin":13,"end":26},"obj":"1604"},{"id":"T92","span":{"begin":51,"end":64},"obj":"1604"},{"id":"T93","span":{"begin":1121,"end":1129},"obj":"2"},{"id":"T94","span":{"begin":298,"end":307},"obj":"2"}],"namespaces":[{"prefix":"_base","uri":"http://purl.bioontology.org/ontology/NCBITAXON/"}],"attributes":[{"subj":"T91","pred":"source","obj":"MicrobeTaxon"},{"subj":"T92","pred":"source","obj":"MicrobeTaxon"},{"subj":"T93","pred":"source","obj":"MicrobeTaxon"},{"subj":"T94","pred":"source","obj":"MicrobeTaxon"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"MicrobeTaxon","color":"#bfec93","default":true}]}]}}
