Fig. 2From: Effects of plasma-activated Ringer’s lactate solution on cancer cells: evaluation of genotoxicityCell viability of HeLa cells treated with buffered lactec with different pH values. Lactec solutions were pre-treated with phosphate buffer 7.2 or citrate buffer to adjust the pH value as 5.1 to 6.2. HeLa cells were treated with buffered and untreated-lactec solution for 2 h. The cell survival test was performed 24 h after changing the mediumBack to article page
