Fig. 2From: Platelet factor 4 polyanion immune complexes: heparin induced thrombocytopenia and vaccine-induced immune thrombotic thrombocytopeniaBinding of PF4 and heparin is a stoichiometrically driven phenomenon. Both PF4 and heparin structure and images created using Mol* (D. Sehnal, S. Bittrich, M. Deshpande, R. Svobodová, K. Berka, V. Bazgier, S. Velankar, S.K. Burley, J. Koča, A.S. Rose (2021) Mol* Viewer: modern web app for 3D visualization and analysis of large biomolecular structures. Nucleic Acids Research. doi: https://doi.org/10.1093/nar/gkab314). The structure and information of PF4 (1F1F9Q) was obtained from RCSB PDB (https://www.rcsb.org/structure/1f9q, accessed in May 2021). The structure and information of representative heparin was obtained from RCSB PDB (https://www.rcsb.org/structure/3irl, accessed in May 2021)Back to article page
