RECOVERY
5 different levels of target protein spiked in samples were evaluated for recovery experiments to determine the range of recovery and calculate the average recovery rate.
LINEARITY
5 different levels of target protein spiked in samples were evaluated for recovery experiments to determine the range of recovery and calculate the average recovery rate. Subsequently, the 5 samples were diluted to 2-fold, 4-fold, 8-fold, and 16-fold 10 concentrations, and recovery experiments were performed again to evaluate the range and average recovery rate at different dilution factors.
PRECISION(%)
Intra-assay precision (Precision within an assay): Low, mid range and high levels of the samples were tested 20 times on one plate, respectively.
Inter-assay Precision (Precision between assays): Low, mid range and high levels of the samples were tested on 3 different plates, 20 replicates in each plate, respectively.
