Abstract

The ability of hepatic plasma membranes to bind desialylated glycoproteins as a prelude to transport and catabolism has been reported earlier. The present study describes the purification, by affinity chromatography, of an hepatic protein which retains the characteristic binding properties associated with the membranes. The isolated material, which is watersoluble and free from lipids, has been identified as a glycoprotein in which 10 % of the dry weight consists of sialic acid, galactose, mannose, and glucosamine in a molar ratio of 1:1:2:2. The integrity of the terminal sialic acid residues and the presence of calcium were shown to be absolute requirements for binding. Physical chemical studies indicated a high degree of aggregation in the final, water-soluble preparation.

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.
