Splet07. avg. 2015 · By employing molecular barcodes, polymerase artifacts generated during PCR can be distinguished from sequence variants present in original molecules. This barcoding has the potential to increase the detection accuracy for mutations at 1 % fraction or lower by removing low level false positives [ 8, 12, 13 ]. Splet19. nov. 2024 · The polymerase chain reaction (PCR) is widely used in modern biology and medicine. However, PCR artifacts can complicate the interpretation of PCR-based results. The internal transcribed spacer (ITS) region of the ribosomal RNA gene cluster is the consensus fungal barcode marker and suspected PCR artifacts have been reported in … SpletThe following are common PCR artifacts: Primer dimers Primer dimers are formed through self-complementarity at the 3' end of the amplification primers. Primer dimers are suspected if product is produced in a template-free reaction (negative control). To avoid primer dimers, primers shouldn't have complementarity at their 3' ends. Chimeric PCR ... litchfield wells fargo
