Über die Isolierung eines Metamorphose-Hormons der Insekten in kristallisierter Form
Open accessAbstract
Aus Seidenspinner-Puppen wurde durch Methanolextraktion und Anreicherung in Bezug auf das im Test am abgeschnürten Abdomen von Calliphora-Larven wirksame Prinzip ein kristallisierter einheitlicher Stoff vom Schmp. 235—237° erhalten, der im Calliphora-Test mit 0,0075 γ wirksam ist. Wie Versuche an Saturniiden-Puppen (C. M. Williams) zeigten, handelt es sich um das Hormon der Prothorakaldrüsen.

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.
