Isolation of two forms of basement membrane proteoglycans.
Open accessAbstract
Sequential extractions of the basement membrane producing Engelbreth-Holm-Swarm tumor yielded heparan sulfate proteoglycans with different size core proteins, but the same size heparan sulfate side chains. Saline, a nondenaturing solvent, extracted a small high density proteoglycan with a heterodisperse core protein of Mr = 95,000-130,000 whereas subsequent extraction with 7 M urea, a denaturing solvent, removed a large, low density proteoglycan with a Mr = 350,000-400,000 protein core. The denaturing conditions required for extraction of the large proteoglycan suggest that it interacts strongly with other basement membrane components. Antibodies to these proteoglycans cross-react with both proteoglycans, but the large proteoglycan has additional antigenic sites not present on the small proteoglycan. These proteoglycans may be derived from the same or similar gene products.

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.
