High density lipoproteins (HDLs; d= 1.063-1.21 g/ml) were isolated by ultracentrifugation and radiolabeled with '"In. The in vitro binding onto platelets from healthy volunteers (it=15) and patients (n=36) with heterozygous familial hypercholesterolemia (FH) was investigated. Binding was saturable and indicated high-affinity binding sites, which bound 1,882±361 ng protein of '"In-HDL/lC platelets (dissociation constant [£ d
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
