Extraction and Solubilization Methods Suitable for Proteomic Analysis of Common Bean Seed of Ivory Coast
Bibliographic record
Abstract
The extraction and solubilization of proteins from seeds of Phaseolus vulgarisms for two-dimension polyacrylamide gel electrophoresis (2D-PAGE) and analysis by mass spectrometry are very sensitive procedures. In this study, we used two methods of extraction and solubilization of proteins, the urea/thiourea method and the trichloroacetic acid (TCA)/acetone precipitation method, in order to determine their effectiveness in separating proteins from bean seeds by 2D-PAGE. In both methods, proteins were well separated by 2D PAGE with minor variations in the protein pattern. These two extraction methods showed that it was possible to separate hundreds of very resolvent proteins by 2D electrophoresis. A protein spot was selected on the 2D-PAGE gel, digested with trypsin and analyzed by mass spectrometry (LCMS/ MS). The results suggest that thiourea/urea and TCA methods were effective and reliable for the extraction and solubilization for 2D analysis of proteins from seeds of Phaseolus vulgaris .

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
