Monitoring the structure of these molecules is crucial for developing new therapeutics, characterizing interactions with antigens or receptors, and explaining potential changes in activity between antibody production batches. However, commonly used biophysical approaches provide only low-spatial-resolution information, and conventional structural biology techniques such as crystallography and cryo-electron microscopy (cryo-EM) are difficult to apply to these highly dynamic proteins. Solution nuclear magnetic resonance (NMR) spectroscopy is the method of choice for structural studies of flexible proteins at atomic resolution; however, it has traditionally been limited to low-molecular-weight biological systems. In this review, we present recent advances in NMR spectroscopy and advanced isotopic labeling methods that have enabled the atomic-resolution study of both the crystallizable (Fc) and antigen-binding (Fab) fragments of antibodies. We show how NMR is becoming a powerful tool for investigating full-length mAbs at an atomic level, opening up new possibilities for the characterization and in-depth quality control of therapeutic antibodies in solution.<\/jats:p>","DOI":"10.3390\/biom16060840","type":"journal-article","created":{"date-parts":[[2026,6,9]],"date-time":"2026-06-09T00:43:54Z","timestamp":1780965834000},"page":"840","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Recent Advances in Atomic-Resolution NMR Investigations of Monoclonal Antibodies"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3317-2963","authenticated-orcid":false,"given":"B\u00e9atrice","family":"Vibert","sequence":"first","affiliation":[{"name":"Institut de Biologie Structurale (IBS), Universit\u00e9 Grenoble Alpes, CNRS, CEA, 38044 Grenoble, France"},{"name":"Integrated Drug Discovery Department, Sanofi R&D, 94400 Vitry-sur-Seine, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faustine","family":"Henot","sequence":"additional","affiliation":[{"name":"Integrated Drug Discovery Department, Sanofi R&D, 94400 Vitry-sur-Seine, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oriane","family":"Frances","sequence":"additional","affiliation":[{"name":"Integrated Drug Discovery Department, Sanofi R&D, 94400 Vitry-sur-Seine, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3278-3639","authenticated-orcid":false,"given":"J\u00e9r\u00f4me","family":"Boisbouvier","sequence":"additional","affiliation":[{"name":"Institut de Biologie Structurale (IBS), Universit\u00e9 Grenoble Alpes, CNRS, CEA, 38044 Grenoble, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1533","DOI":"10.1016\/j.xphs.2016.09.003","article-title":"Technical Decision Making with Higher Order Structure Data: Perspectives on Higher Order Structure Characterization from the Biopharmaceutical Industry","volume":"105","author":"Weiss","year":"2016","journal-title":"J.
