The AGM eBook is available on the NCBI Bookshelf.

The Assay Guidance Manual (AGM) eBook is a free, best-practices online resource devoted to the successful development of robust, early-stage drug discovery assays.

The manual was adapted from documents developed by the drug discovery industry (Eli Lilly and Company and Sphinx Pharmaceuticals, Inc.) that were designed to collect institutional knowledge and provide step-by-step guidance on planning and creating projects for high-throughput screening, lead optimization, and early phases of regulated drug development. The AGM has now been expanded into a unique, user-friendly collection of over 50 chapters of well-tested knowledge, much of which is being documented for the first time. Methods outlined in the manual address appropriate statistical ways to analyze assay results and accommodate minor changes to assay protocols to ensure robustness.

Investigators worldwide can use the manual to design biologically and pharmacologically relevant assays for high-throughput screening and lead optimization to evaluate collections of molecules that modulate the activity of biological targets, pathways and cellular phenotypes.

Our staff manage the content of the manual with input from industry, academic, and government experts. The editorial board consists of members from across the preclinical translational science spectrum. More than 100 authors from around the world have contributed content to this free resource, which is updated regularly and housed by the National Library of Medicine. The AGM has proven to be a widely used resource for those working in drug discovery. Since 2017, it has received more than 30,000 monthly views by scientists from both public and private sectors from over 130 countries.
