WebThere are two ways to perform a linearity-of-dilution experiment. Traditional method. The traditional method involves using a low-level sample containing a known spike of analyte, and then testing several different dilutions of that sample in the chosen sample diluent. Alternative method. Web4. Avoid contamination. Having low coefficient of variability (%CV) between your sample replicates is key to a successful and well run assay. Keep %CV between duplicates low by using fresh pipet tips for each addition to the assay. New tips can prevent cross-contamination between wells, which in turn can keep the background and %CVs low and ...
