<i>In situ</i>detection of a novel lysozyme monoclinic crystal form upon controlled relative humidity variation
Abstract
<jats:p>The effect of relative humidity (rH) on protein crystal structures, an area that has attracted high scientific interest during the past decade, is investigated in this study on hen egg-white lysozyme (HEWL) polycrystalline precipitates<jats:italic>via in situ</jats:italic>laboratory X-ray powder diffraction (XRPD) measurements. For this purpose, HEWL was crystallized at room temperature and pH 4.5, leading to a novel monoclinic HEWL phase which, to our knowledge, has not been reported before. Analysis of XRPD data collected upon rH variation revealed several structural modifications. These observations, on a well-studied molecule like HEWL, underline not only the high impact of humidity levels on biological crystal structures, but also the significance of in-house XRPD as an analytical tool in industrial drug development and its potential to provide information for enhancing manufacturing of pharmaceuticals.</jats:p>
