Distribution of annionic sites in glomerular basement membranes: their possible role in filtration and attachment.
Open accessAbstract
Lysozyme (pI = II) has been used to identify anionic sites in the glomerular capillary wall. A solution of 1-3% lysozyme was perfused into the left kidney at varying rates. After perfusion, the kidney was fixed in situ and processed for electron microscopy. Lysozyme was seen as an electron-dense deposit which was not present when succinylated lysozyme (pI = 4.5) or myoglobin (pI = 6.9) was perfused instead of native lysozyme. First, the epithelial cell plasma membrane was outlined by a 300-400 A electron-dense layer. Second, there were discrete dense deposits in the subepithelial portions (lamina rara externa) of the basement membrane which, in normal sections, extended from the epithelial cell membrane to the lamina densa and, in grazing section, formed a continuous reticular pattern.

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.
