The adherent colon carcinoma cell line
HT-29 (ATCC/LGC GmbH, Wesel, Germany) was cultivated in
McCoy’s 5A medium (Gibco, Carlsbad, CA, USA) with either 10%
fetal calf serum (FCS) (Biochrom AG, Berlin, Germany) for magnetic accumulation or cell death kinetics, or 10%
Panexin NTA (PAN-Biotech GmbH, Aidenbach, Germany) whenever analyses of DAMPs or cytokines were planned, to minimize interactions with the detection. In preceding experiments, we confirmed that
HT-29 cells showed similar behavior, no matter if cultivated in medium containing FCS or Panexin. The monocytic cell line THP-1 (TIB-202; American Type Culture Collection [ATCC], Manassas, VA, USA) was cultured in Roswell Park Memorial Institute (RPMI) 1640 medium supplemented with 2 mM glutamine, 10% FCS (Biochrom AG), 100 U/mL
penicillin, and 100 μg/mL
streptomycin (Gibco
®). All cells were cultured in a cell culture incubator (INCOmed, Memmert, Schwabach, Germany) at 37 °C, 5% CO
2 and 95% humidified air. Cells were regularly checked for mycoplasma contamination using PCR kit Venor
®GeM (Minerva Biolabs GmbH, Berlin, Germany). Before every experiment, count and viability was analyzed using MUSE
® Count & Viability assay kit in
MUSE cell Analyzer (Merck-Millipore, Billerica, MA, USA). A cell viability above 95% was required to start an experiment.
