New approach improves sensitivity of DNA sequencing, producing more reliable results

Polymerase chain reactions (PCR) are one of the most common tools used in molecular biology labs worldwide. This technique allows researchers to amplify, or increase, the amount of DNA in a sample so that they have more to work with. To keep track of the original molecules from a sample, chemical ‘barcodes’ are added. While barcodes serve an important purpose they can lead to errors and interfere with results. To prevent these cross-reactions a small team of international researchers have devised an ingenious method to ‘hide’ the barcodes when needed, leading to increased sensitivity and more reliable results.
