Journal Article
Bott, T., Shaw, G., & Gregory, S. (2023). A simple method for testing and controlling inhibition in soil and sediment samples for qPCR. Journal of Microbiological Methods, 212, Article 106795. https://doi.org/10.1016/j.mimet.2023.106795

The presence of polymerase-chain-reaction (PCR) inhibitors in many environmental samples can make reliable and repeatable quantitative-polymerase-chain-reaction (qPCR) analysis difficult without sample dilution. To estimate an optimal sample dilution... Read More about A simple method for testing and controlling inhibition in soil and sediment samples for qPCR.
