Crystal soaking vs co-crystallization

WebFeb 20, 2013 · In principle there are four methods to include the substrate into the crystallization trials: 1) co-crystallization 2) ligand soaking 3) micro or macro seeding 4) endogenously bound ligands. The first method is co-crystallization. Here, normally the substrate is added prior to crystallization to the protein solution. WebSep 19, 2024 · or soaking (Hassell et al., 2007).
