Protocol for measuring cellular energetics through noncanonical amino acid tagging in human peripheral blood and murine tissue immune cells
Bibliographic record
Abstract
Cellular metabolism dictates immune cell function, yet we lack tools to functionally profile immunometabolism in low-yield, complex samples. We present a flow cytometry-based protocol for measuring cellular energetics through noncanonical amino acid tagging (CENCAT) in human peripheral blood and murine tissue immune cells. We describe steps for sample preparation, metabolic inhibition, protein synthesis analysis using click chemistry, immunophenotyping, and calculation of metabolic dependencies. For complete details on the use and execution of this protocol, please refer to Vrieling et al. 1 • Instructions for preparing human PBMCs and murine tissues for metabolic profiling • Protocol for βES incorporation in nascent proteins under metabolic inhibition • Step-by-step guide to fluorescent tagging of nascent proteins via click chemistry • Procedure for calculating relative cellular glucose and mitochondrial dependence 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.
