Abstract
Background: Capillary microsampling (CMS) has been used for quantitative bioanalysis of small molecules; however, there is no report of applying this technique in the bioanalysis of antisense oligonucleotides (ASOs). Results: A CMS liquid chromatography–tandem mass spectrometry method was successfully developed and validated for the quantification of ASO1 in mouse serum. The validated method was applied in a safety study in juvenile mice. Equivalent performance between CMS samples and conventional samples was demonstrated in the mouse study. Conclusion: This work is the first to report using CMS for liquid chromatography–tandem mass spectrometry quantitative bioanalysis of ASOs. The validated CMS method was successfully applied to support good laboratory practice safety studies in mice and the CMS strategy has subsequently been applied to other ASOs.

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 it
