Fig. 4From: Cytotoxicity activities and chemical characteristics of exopolysaccharides and intracellular polysaccharides of Physarum polycephalum microplasmodiaPercentages of viable HeLa (a), MCF-7 (b), HepG2 (c) and BAE cells (d) treated with 1 mg/ml polysaccharide samples. Doxorubicin (dox) 50 μg/ml was used as a positive control. Data represent the mean and standard deviation. Note that ‘cr-‘= crude sample and ‘pp-‘= partially purified sample.* indicates a significant difference as compared with the control (p < 0.05)Back to article page
