    Leukocyte common antigens CD45 are large receptors that are abundantly expressed at the surface of all leukocytes. We found that while soluble CD45 binds heparin with high affinity, fibronectin domains FN2 and FN3 bind it with only low affinity. No binding was observed to FN3.

    Leukocytární společné antigeny jsou velké receptory hojně exprimované na povrchu všech leukocytů. Zjistili jsme, že zatímco rozpustná extracelulární forma tohoto antigenu se váže na heparin s vysokou afinitou, isolované fibronektinové domény FN2 a FN3 mají pouze slabou vazbu. Doména FN1 se na heparin vůbec nevázala.
