| Barcoded primers used in multiplex amplicon pyrosequencing bias amplification. Berry D, Ben Mahfoudh K, Wagner M, Loy A. Applied and environmental microbiology. 2011. |
"Barcode-tagged" PCR primers used for multiplex amplicon sequencing generate a thus-far-overlooked amplification bias that produces variable terminal restriction fragment length polymorphism (T-RFLP) and pyrosequencing data from the same environmental DNA template. We propose a simple two-step PCR approach that increases reproducibility and consistently recovers higher genetic diversity in pyrosequencing libraries. |
