Abstract
We describe a simple, powerful, and robust NMR-based method that has the potential to greatly impact the characterization of recombinant protein therapeutics. The method ascertains the bioactive conformational identity of recombinant human granulocyte macrophage-colony stimulation factor (rhGM-CSF) produced in Streptomyces lividans versus Escherichia coli by overlaying their 2D 1H,15N HSQC correlation spectra. An identical match of all resonances implies that rhGM-CSF from both processes share indistinguishable conformations that correlate with in vitro activity. The result of this method is unique among existing methods. It can detect and quantify the active ingredient. Moreover it provides a complete assessment of the conformation with high sensitivity to minor structural changes.

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
