The antibody reacted with normal human platelets in the presence of quinine, as shown by flow cytometry. The reactions of the antibody with CHO cells expressing all-human GPIIb/IIIa (H/H), all-rat GPIIb/IIIa (R/R), or human/rat mixed GPIIb/IIIa integrins (H/R, R/H) were studied by flow cytometry. Quinine dependent antibody binding occurred with constructs H/H and H/R, but not with R/R or R/H (Bougie et al., 2009; PMID: 18948570). The crystal structures of the Fab fragment and its complex with quinine were determined. Quinine induced structural modifications of the Fab fragment; the authors propose that quinine remodels the Fab paratope and enables binding to the platelet GPIIb/IIIa. The monovalent KD values for quinine binding to the IgG fragment measured was 24 nM (Zhu et al., 2015; PMID: 26282540).
