Antibiofilm and Antioxidant Activity of Propolis and Bud Poplar Resins versus Pseudomonas aeruginosa

Table 3

Cytotoxic concentration (CC50) of different extracts on HeLa, BEAS-2B, and A549 cell lines and human monocytes.

Cytotoxicity was tested by the determination of the cell ATP level by a bioluminescent method after 24 h of incubation. CC50 is the concentration required to reduce the live cell number by 50% compared to the untreated controls.
