Abstract

Summary α s -Casein and κ -casein have been freed of major contaminants, judged by starch-gel-urea electrophoresis. The α s -casein was prepared by a urea-sodium chloride procedure with a final precipitation of impurities by ethanol. κ -Casein was prepared by extraction of whole casein with urea-sulfuric acid supplemented with ethanol precipitation. Electrophoretic mobility, pH of minimal solubility salt-free (isoionic point), and with 0.1 m NaCl (isoelectric point), ultraviolet absorption, and interaction with calcium ions are reported.

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.
