Abstract
Accurate measurement of antigen-positive cells by flow cytometry can be hampered by background fluorescence of antigen-negative cells and other particles (e.g., debris). This article focuses on three major causes of background (autofluorescence, spectral overlap, and undesirable antibody binding) by reviewing individual aspects of flow cytometric measurements that contribute to these causes. The appropriate use of controls facilitates a thorough understanding of these contributing factors as well as the development of robust cell labeling protocols intended for routine flow cytometric analysis. We present a set of recommendations that enables the user to develop an optimized cell labeling protocol that minimizes background and maximizes the ability to reliably distinguish between a positive and a negative population of cells. These recommendations are also intended to augment existing guidelines designed to aid in the formulation of a consensus regarding the utility of flow cytometry for the analysis of clinical samples.

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
