Isolation and Composition of Staphylococcal Alpha Toxin
Abstract
SUMMARY: A method is described for the preparation, on a laboratory scale, of staphylococcal alpha toxin having a purity of about 70% and in a yield of 40%. The method entails ammonium sulphate fractionation followed by curtain electrophoresis. The toxin so obtained contains two impurities, one of which can be removed electrophoretically, and the other ultracentrifugally. The toxin itself is a protein of molecular weight 44,000. It contains most of the usual amino acids which vary in amount from 4 residues for histidine to 44 for aspartic acid. Although electrophoretically heterogeneous its electrophoretic components produce the biological effects heterogeneous associated with alpha toxin. As by-products of purification, two other proteins were isolated in crystalline form. Their significance for pathogenicity, if any, remains to be determined.

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.
