Abstract
Objective To extract human NT-proBNP from the E.coil which express GST-NT-proBNP fusion protein and identify the protein after purification,while its stability was studied.Methods BL21-pGEX-4T-3-NT-proBNP was amplified and induced by IPTG.The expression was purified by affinity chromatography through GSH-agarose and identified by SDS-PAGE and Western blot.The immunoreactivity and stability of the fusion protein was analyzed by commercial immune analyzer platform.Results The expression level of GST- NT-proBNP was high with good solubility.The fusion protein appeared in SDS-PAGE with molecular mass of 34 600 and could be recognized by NT-proBNP immune analyzer with good activity and stability.Conclusion Enough quantity of NT-proBNP could be produced in recombinant GST fusion protein form.Under non-denatural condition,GST-NT-proBNP with good immunoreactivity and stability could be obtained.

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
