Splet09. maj 2011 · An additional second PCR amplification step (+10 cyles) was performed to the library S 8. The amplification produced high numbers of duplicate reads (Table 1), with library S 8 most affected. We used these libraries to evaluate the robustness of our method against PCR artefacts. Datasets S 2-S 5 represent in silico modifications of the S 1 library.

SpletPCR bias and artifact formation can occur in multitemplate PCR, and provide incorrect information on the abundance and diversity of genes. PCR bias and artifact formation occur at a higher rate during the last few cycles of the reaction, and therefore can be avoided by stopping the PCR earlier.
