Fig. 3From: Nitric oxide induced by Indian ginseng root extract inhibits Infectious Bursal Disease virus in chicken embryo fibroblasts in vitroDetermination of non-cytotoxic concentration of aminoguanidine for CEF; CEF growing in 96-well plates were treated with different concentrations of aminoguanidine, four wells per concentration. The test was repeated thrice independently and the mean of the values was used for determining the concentration-dependent cytotoxicity of aminoguanidine. The non-cytotoxic dose and median lethal dose were calculated from the standard curveBack to article page
