LysoTracker Staining to Aid in Monitoring Autophagy in <i>Drosophila</i>
Bibliographic record
Abstract
LysoTracker is an acidotropic dye that stains cellular acidic compartments, including lysosomes and autolysosomes. LysoTracker has been used to detect autophagy-associated lysosomal activity in Drosophila tissues including the fat body, midgut, salivary gland and ovary, as well as in Drosophila cell culture. A low level of LysoTracker staining can be observed under resting or well-fed conditions, and is increased following autophagic stimuli such as starvation. Here we provide a protocol for examining LysoTracker levels in Drosophila cultured cells in vitro using standard cell culture methods and flow cytometry. We also describe how to examine LysoTracker in fixed and nonfixed Drosophila tissues using fluorescence microscopy. Ovary tissue is used as an example. Dissections of ovaries are relatively easy to perform, given their large size.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
