Phase-Partition Fixation and Staining of Drosophzla Eggs
Abstract
Aqueous solutions of alcohol-acetic acid-formalin or glutaraldehyde-acrolein were shaken with heptane and heptane phase used for fixation. Phase-partition fixation is akin to fixation with vapor. The organic solvent, immiscible with water, penetrates hydrophobic membranes and carries the fixative in contact with water phase of the tissue. Only the fixative enters the tissue, without changing the ionic and water-soluble substance concentrations in the tissue. The quality of this fixation for optical or electron microscopy was as good as that of any conventional fixation method. Staining with basic fuchsin after 2 N HCl hydrolysis gave brilliant staining of nuclei, more intense than that with Feulgen reagent, while cytoplasm remained nearly colorless. Fixing and staining procedures for Drosophila eggs are given.

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.
