Reproducibility matters…


In science, the buzz around the reproducibility topic has been going on for some time now. Back in 2010 an article in The New Yorker called “The Truth Wears Off” addressed the concern of which results to believe when so-called validated findings could not be proven or replicated and led to retraction of scientific publications. (1)

In 2013, a published article by Vasilevsky et al. showed that around half of the scientific resources used in published articles were unidentifiable. The authors stressed the need to increase accessibility of the material resource information to aid in obtaining reproducible results. (2) They also provided guidelines for reporting research resources, for use by reviewers, authors and publishers to increase transparency and reproducibility. (3)

In 2016, Monya Baker’s survey was published in Nature, lifting the lid on reproducibility in research. Of the 1,576 researchers who participated in the brief online questionnaire, more than 70% have tried and failed to reproduce another scientist’s experiments. Plus, over half have failed to reproduce their own experiments. (4)

Obtaining results you can trust is important because reproducible and reliable studies lay the foundation for future scientific endeavors to build upon. We have created two infographics about irreproducibility, one focusing on nucleic acid isolation and the other on PCR-based assays. In addition, we have 5 key RNA infographics, each focusing on a different step in the gene expression analysis workflow, to help you obtain the most consistent and dependable results possible.

Step 1: RNA by the numbers – looks at the RNA distribution within the mammalian cell, the RNA sizes and average yields of total RNA from various sources

Step 2: The DO’s and DON’Ts of working with RNA – includes how to handle, store and stabilize your RNA

Step 3: Describes how to best disrupt and homogenize various starting materials to ensure successful RNA isolation

Step 4: Provides you with special considerations for isolating RNA from different sample sources

Step 5: Shows you tools and methods for RNA quantification and analysis
