摘要：A specific, accurate, and sensitive double antibody radioimmunoassay for measuring human apolipoprotein (apo) C-III has been developed. Anti-apoC-III(1) developed in rabbits cross-reacted completely with apoC-III subspecies. Analytical isoelectric focusing of delipidated triglyceride-rich lipoproteins (TRL) was done to assess the percentage of total apoC-III mass comprised by apoC-III(0), C-III(1), and C-III(2), and the data were used to compute the absolute plasma TRL apoC-III subspecie concentration. Total plasma apoC-III was 11.1 +/- 0.9 mg/dl (mean +/- SEM) in 29 normolipidemic healthy subjects; 21.3 +/- 4.9, 27.5 +/- 2.2, and 53.6 +/- 7 mg/dl in 3, 16, and 13 patients with primary types III, IV, and V hyperlipoproteinemia, respectively, and significantly (P 1.006 g/ml). ApoC-III comprised significantly more of HDL(2) than HDL(3) protein (7.3 +/- 0.2 versus 1.6 +/- 0.2%, respectively, P
