A Solubility Optimization Protocol for Two-Dimensional Gel Electrophoresis of Cardiac Tissue
Bibliographic record
Abstract
We outline a strategy for the optimization of buffer conditions for the solubilization, extraction, and isoelectric focusing (IEF) of proteins from cardiac tissue for two-dimensional gel electrophoresis (2DE). This strategy, which involves altering both the extraction and IEF buffers, allows one to ensure representation of the proteome that is as complete as possible. Initial buffer choices are given, as well as basic protocols for modifications. Although these conditions have been effectively demonstrated for human myocardium, in principle this procedure can be used for the initial screen of any new sample of tissue or cultured cells.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
