Using the <em>Sleeping Beauty</em> Transposon System for Doxycycline-inducible Gene Expression in RAW264.7 Macrophage Cells to Study Phagocytosis
Bibliographic record
Abstract
phosphate and inhibits phagocytosis. One benefit is that generating stable cell lines is substantially faster than selecting for random integrations. Without FACS, the method typically gives ~50% of the cells that are transfected; with sorting, this approaches 100%. This makes phagocytosis experiments easier since more cells can be analyzed per experiment, allowing for population-based measurements where a ~10% transient transfection rate is insufficient. Finally, using the doxycycline-promoter allows for low near endogenous expression of proteins or robust overexpression. Key features • This protocol builds on the protocols and reagents developed by Kowarz et al. [1] and extends it to using RAW macrophages. • Allows for the rapid generation of stably induced cell lines. • This protocol also determines the phagocytic index and efficiency.

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.
