Abstract
Western blotting is a method widely used in cell and molecular biology for the specific detection of proteins in biological samples. It is time-consuming and normally takes up to 2 days to complete. This protocol introduces a more time-efficient method to complete western blots, covering the preparation of protein extracts (including strategies for solubilization), electrophoretic separation of proteins, transfer of proteins to the membrane, and probing with antibodies. We describe an SDS-PAGE protocol that achieves a gradient-like separation of proteins (10-400 kDa) on a single-percentage polyacrylamide gel in only 45 min. Additionally, we present a rapid (10-14 min) semi-dry transfer of proteins from standard Tris/glycine polyacrylamide gels onto a membrane using homemade Tris/HEPES- or Tris/EPPS-based buffers. © 2023 Wiley Periodicals LLC.

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
