Oligomerized Phospholipid Bilayers as Semipermanent Coatings in Capillary Electrophoresis
Bibliographic record
Abstract
Double-chained surfactants form semipermanent coatings that prevent protein adsorption in capillary electrophoresis (CE). To make such coatings more permanent, vesicles of the unsaturated phospholipid 1,2-dioleoyl-sn-glycero-3-phosphocholine were prepared and subjected to free-radical-initiated polymerization, both inside the capillary and in free solution. The latter generated oligomers of 2-5 units based on ESI-TOF MS, and formed the more stable coating in CE. Rinsing the capillary with a solution of the ex situ oligomerized DOPC suppressed EOF (0.8 x 10(-)(8) m(2)/V.s) for more than 20 h, whereas in situ oligomerized electroosmotic flow (EOF) suppressed the EOF for only 10 h. Mixtures of anionic and cationic proteins were separated under neutral pH and low ionic strength buffer with efficiencies of 480,000-930,000 plates/m and recoveries of 75-99%.

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.
