Protocol to evaluate translation inhibition in Candida species using fluorescence microscopy and flow cytometry
Bibliographic record
Abstract
Translation inhibitors have therapeutic potential against Candida species. Here, we present a protocol to measure translation inhibition in Candida spp. We describe steps for employing an alkynylated methionine analog, L-homopropargylglycine (HPG), that becomes incorporated into newly synthesized proteins. We then detail procedures to perform a click reaction of the alkyne with a fluorescent azide, which is visualized using fluorescence microscopy and quantified by flow cytometry. For complete details on the use and execution of this protocol, please refer to Puumala et al., 1 Fu et al., 2 and Iyer et al. 3 • Protocol for measuring translation in Candida species • Method to incorporate a methionine analog (HPG) into newly synthesized proteins • A click reaction of the alkyne with a fluorescent azide produces fluorescent cells • Visualization of cell signals with microscopy and quantified by flow cytometry Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
