Improving Reproducibility: Best Practices for Antibodies, Cell Lines, and Small Molecules

Taking several small steps can reduce the risk researchers unknowingly take when running an experiment. Some of these steps are simply asking smart questions before purchasing products or recording product information as reagents are opened. Sigma-Aldrich PhD Scientists recently authored the following paper outlining best practices to ensure researchers are using quality antibodies, cell lines & small molecules to increase reproducible & translatable experimental results.

The State of Translational Research

This report, conducted in collaboration with the American Association for the Advancement of Science (AAAS), presents the views of more than 600 self-described academic translational researchers. Together, we aim to better understand current practices, barriers to progress and how to advance the field.


Partnership with The Scripps Research Institute

Our partnership with Scripps allows immediate, day-of-publication access to Scripps researchers’ discoveries for the synthesis and analysis of potential drugs. The partnership enables widespread access to those reagents for the translational research community.

Ascentis® Express has proven to be an exceptional HPLC column for pharmaceutically relevant compounds. Their substantially lower backpressure than sub-2 micron columns allows them to be used at much higher flow rates for fast drug discovery. Furthermore, the column length can be increased to improve resolution without exceeding the capabilities of conventional HPLC equipment. Process chemists find the lifetime and ruggedness of Ascentis Express to be a key advantage for walk-up LC-MS systems.
