Preparation, Manipulation, and Pulse Strategy for One-Dimensional Pulsed-Field Gel Electrophoresis (ODPFGE)
Bibliographic record
Abstract
The preparation and manipulation of very large DNA molecules for pulsed-field gel electrophoresis (PFGE) requires more care than normally used for smaller molecules. The general protocol used is the preparation of DNA directly in solid agarose blocks (plugs) or beads. Intact cells are encapsidated in agarose (plugs or beads) and are treated with different combinations of enzymes and detergent to remove cell walls, membranes, RNA, proteins, and other materials in order to obtain naked DNA. This is possible because detergent and enzymes can diffuse by Brownian motion through the agarose pores of the plug, whereas the large pieces of DNA cannot and remain sequestered inside the plug. Here, we give detailed protocols of preparation for yeast and mammalian DNA. In addition, we describe the power supplies, switchers, gels, and gel trays required for one-dimensional pulsed-field gel electrophoresis (ODPFGE), as well as the pulse strategies used for the separations.

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.
