Protocol for antibody optimization and panel design in high-dimensional multiplexed immunofluorescence imaging
Bibliographic record
Abstract
The rise of spatial biology technologies is advancing our ability to study cellular interactions within native tissue contexts using antibody-based multiplexed imaging. Here, we present a protocol for designing and optimizing a suitable antibody panel, with a specific focus on the PhenoCycler-Fusion system. We outline steps for antibody selection, optimization, and validation, as well as reporter plate preparation and cycle generation for image acquisition. This protocol incorporates key considerations for robust panel development for spatial profiling of tissues. For complete details on the use and execution of this protocol, please refer to Abraham et al. 1 • Steps for selecting antibodies for immunofluorescence imaging of tissues • Guidance for validating antibody performance in single and multiplexed imaging formats • Recommendations for assigning barcodes based on autofluorescence and antigen abundance • Steps for reporter plate setup and cycle design for imaging with PhenoCycler-Fusion Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

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.
