22. Negative controls unveil a hidden culprit in a problematic experiment (mini-series: reading-14)

We continue our deep exploration into negative controls and their importance in troubleshooting life-science experiments. We follow a real-life story of an experiment that yielded unexpected results. Through the third troubleshooting experiment utilizing negative controls, the experimenters finally uncovered the culprit. We discuss how negative controls helped identify the problem and pave the way for further investigation.     This is Part 14 of the reading mini-series "Let’s read a paper written by Nobel Prize Laureates, 2023."    (My email is active.
