Molecular deformation and free‐solution electrophoresis of DNA‐uncharged polymer conjugates at high field strengths: Theoretical predictions Part 2: Stretching
Bibliographic record
Abstract
DNA sequencing by electrophoresis can be dramatically sped up by overcoming the need for the sieving medium. Normally it is possible to separate DNA based on size in free solution; however, not end-labeled free-solution electrophoresis (ELFSE) uses a neutral drag-tag molecule to make it possible. In experiments to date, the drag-tag and DNA together form a random coil conformation; while with future generation drag-tags and high fields, deformation of this conformation may occur. In the first paper in this series we investigated the conditions under which the DNA and label become hydrodynamically distinct (or segregated), based on a theoretical approach developed for the electrophoresis of polyampholytes. In this paper we study further deformation wherein either the DNA and/or a polymeric label stretch. We show that deformation may dramatically improve the capabilities of ELFSE, especially when both the DNA and a polymeric drag-tag fully stretch; however, reaching these regimes will require extremely high field intensities, something that only microchip technologies may be able to achieve.

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.
