The following shows example data for study 123 in a report table. This report includes summary statistics (i.e., average, standard deviation, coefficient variation) for each plate and an EC50 value for the entire assay. The grey cells in plate 1 are cells that do not contain the NHK cells. Neutral Red Cytotoxicity Assay Results (Relative Absorbance Data) |
