Annexin A5—effect of aPL antibody.
(A) An atomic force image of the 2-dimensional crystallization of annexin A5 over a phospholipid bilayer. Each of the circular structures that compose each row is a trimer of annexin A5. The crystal covers nearly 100% of the phospholipid bilayer.
(B) The effects of a monoclonal aPL antibody together with β2GPI on the crystal structure of annexin A5. The aPL-β2GPI results in marked disruptions of the annexin A5 crystal.
Abbreviations: aPL, antiphospholipid; β2GPI, β2-glycoprotein I.
