Apolipoprotein B-100 is a constant component of very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), and low density lipoproteins (LDL) in mammalian blood plasma. We have found that each of these classes of lipoproteins includes particles that contain apolipoprotein E (B,E particles) as well as particles that lack this protein (B particles). These two species can be se...

A method is described for the determination of VLDL apolipoprotein B by radial immunodiffusion (RID) in serum supernatants following precipitation of LDL with polyvinylsulphate. The measurement of VLDL apolipoprotein B is based on the incubation of the polyvinylsulphate supernatant with triglyceride lipase (330 kU/l end concentration) for 12-24 hours at 37 degrees C. A good measure of agreement...

familial defective apolipoprotein (apo) b 100 (fdb) causes early-onset coronary heart diseases (chd). it is produced by r3500q mutation of the apob gene resulting in decreased binding of ldl to ldl receptor. we screened the apo b gene for r3500q mutation in 130 hypercholesterolemic patients, among whom 30 patients met criteria of familial hypercholesterolemia (fh). the prevalence of r3500q alle...

VLDL cholesterol concentrations were determined in 1641 male and 608 female and VLDL apolipoprotein B concentrations in 505 male and 211 female company employees in Westphalia aged 17-70 years. VLDL cholesterol and VLDL apolipoprotein B values were found to be distributed with positive skew in both sexes but were higher in men than in women (median in men: VLDL cholesterol 0.30 mmol/l, VLDL apo...
