Cell viability was monitored with the lactate dehydrogenase (LDH) release assay using the CytoTox96® non-radioactive cytotoxicity kit (Promega, Stockholm, Sweden), as previously described [16 (link)]. The samples were analyzed using the Tecan Infinite® F200 plate reader operating with Magellan v7.2 software (Männedorf, Switzerland). The percentage of cell viability was calculated based on the ratio between the absorbance of each sample and the negative control sample.
