Abstract

Low density lipoproteins and the triglyceride-rich lipoproteins of human serum each contain proteins of high molecular weight termed apolipoprotein B, which have previously been thought to be identical. We have isolated four species of apolipoprotein B with unique molecular weights and amino acid compositions. We have assigned numerical designations to these species in a centile system based upon their relative apparent Mr in NaDodSO4. One which we term B-100, with an apparent Mr of 549,000 +/- 7650 (SD) determined by NaDodSO4 gel electrophoresis, predominates in low density and very low density lipoproteins and is also present in chylomicrons from thoracic duct lymph or from plasma. Substantial amounts of two large proteins designated B-74 (apparent Mr 407,000 +/- 5790) and B-26 (apparent Mr 144,500 +/- 8970), which appear to be complementary fragments or constituents of the B-100 protein, are found in the low density lipoproteins of many individuals. A distinct protein, B-48, with an apparent Mr of 264,000 +/- 8150 is a major and constant constituent of chylomicrons from thoracic duct lymph or from plasma.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
