Radioimmunoassay studies of human apolipoprotein E.
This report describes the development and first applications of a sensitive and specific double antibody radioimmunoassay for human apoplipoprotein E (apoE). ApoE was purified from the very low density lipoproteins of hypertriglyceridemic patients by heparin-agarose affinity chromatography, DEAE-cellulose chromatography, and preparative polyacrylamide gel electrophoresis. The purified apoprotei...
متن کاملRadioimmunoassay of apolipoprotein a-ii.
A double antibody radioimmunoassay was developed for apolipoprotein A-II (apo A-II), one of the two major apoproteins of human high density lipoproteins (HDL). Apo A-II contains two identical polypeptide chains linked by a disulfide bond. A specific antiserum was raised in sheep. Tracer apo A-II was radiolabeled with 125I by the Bolton-Hunter technique. Reduction and carboxymethylation of apo A...
متن کاملApolipoprotein E and atherosclerosis: insight from animal and human studies.
Major advances have been made in our understanding of the role of apolipoprotein E (apoE) in the onset and development of atherosclerosis. Increasing evidence from both animal and human studies suggests that apoE is able to protect against atherosclerosis by: a) promoting efficient uptake of triglyceride-rich lipoproteins from the circulation; b) maintaining normal macrophage lipid homeostasis;...
متن کاملAN INVESTIGATION OF HUMAN APOLIPOPROTEIN E POLYMORPIDSMS IN MULTIPLE SCLEROSIS PATIENTS OF IRAN
Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, with a complex etiology that includes a strong genetic component. The chromosome 19q 13 region surrounding the apolipoprotein E (APOE) gene has shown consistent evidence of involvement in MS. In a cross-sectional study, to show the APOE genotype and allele frequency in the MS population of Iran in comp...
متن کاملHeterogeneity of apolipoprotein E epitope expression on human lipoproteins: importance for apolipoprotein E function.
The conformations of apolipoproteins on the surfaces of lipoprotein particles affect their physiologic functions. The conformations of apoE on plasma lipoproteins were examined using a panel of eight anti-apoE monoclonal antibodies (MAbs). The antibodies, which reacted with the major isoforms of apoE (E2, E3, and E4), defined at least five epitopes on apoE. Proteolytic fragments and synthetic p...
