Abstract
Assay validation was performed using four consecutive experiments with the related statistical evaluation. A cell-based assay on microtitre plates measured repeatedly within 1 day and on consecutive days was chosen as the model. The following problems were addressed: (i) choosing an appropriate design on a plate to avoid heterogeneities, (ii) quantification of all sources of variability and (iii) selecting between linear and non-linear parallel line assays. A mixed model was used with the random factors: rows, columns and plates and fixed effect factors with either linear or non-linear parallel line models.
