WebFor the same number of dilutions or replicates on a 5-log range, the potential artifact is only ±8 %. That means for 94% efficiency on a 5-log range, the assay would have a range of 88% to 100% efficiency. To accurately determine the efficiency of a PCR reaction, a 5-log dilution series must be performed. WebThe volume of sample in an assay tube influences absorbance because it dilutes the color reagent that you add to it. Samples containing identical amounts of protein will give different absorbance values if the sample volumes before adding color reagent are different.
