Antifungal activity and loss of cell viability due to treatment with either dhvar2 or L7F. (a) Cell growth over 24 h after addition of either peptide added at T = 0. Black, no peptide; blue, dhvar2; red, L7F, measured as OD600. (b) Yeast viability staining by fluorescent Live (fluorescein diacetate, green)/Dead (propidium iodide, red) reagents. Control, no peptide; dhvar2 and L7F, 250 μg/ml peptide as indicated for 1 h (left) and 6h (right). Scale bars, 50 μm.
