Survival fraction was calculated using the following formula: mean colony counts/cells inoculated × plating efficiency (PE).
Surviving fraction was calculated as: (mean colonies counted)/ cells plated) × (plating efficiency), where plating efficiency was defined as (mean colonies counted)/ cells plated) for unirradiated controls.
Surviving fraction was calculated as (mean colony counts)/((cells inoculated)× plating efficiency)), in which plating efficiency was defined as (mean colony counts)/ cells inoculated for un-irradiated controls).
Plating efficiency was defined as the mean number of colonies divided by the number of inoculated cells for nonirradiated controls.
Plating efficiency was defined as the mean number of colonies divided by the number of plated cells for corresponding nonirradiated cells.
Survival of yeast strains at 37°C was evaluated as plating efficiency, and curves are the mean values from three independent experiments.
Plating efficiency was defined as the mean number of colonies divided by the number of inoculated cells for control cultures not exposed to nimotuzumab or radiation.
The surviving fraction was calculated as: (mean number of colonies)/(number of plated cells × plating efficiency).
The surviving fraction was calculated as: (mean number of colonies)/(number of inoculated cells × plating efficiency).
The mean value was calculated and used for correction for single-cell survival in flasks with plating efficiency below 1 according to a formula previously published (Elkind et al. 1965).
