Purificación de GFP en reacciones cell-free para actividad docente // GFP purification from cell-free reactions for educational purpose v1
Bibliographic record
Abstract
Este protocolo describe una actividad educativa que tiene como fin explicar las bases de la purificación de proteína con materiales que pueden ser usados sin la infraestructura tradicional de un laboratorio. En pocas palabras, una proteína de interés (en este caso, 6xHis-sfGFP) se produce en extractos cell-free toda la noche. Al día siguiente, se purifica usando el kit NEBExpress Spin Columns y de acuerdo a las instrucciones del fabricante. Todas las etapas de centrifugación (unión, lavado y elución) se realizan usando una centrífuga de mano fabricada con impresión 3D. La actividad dura dos horas. This protocol describes an educational activity to explain the basics of protein purification with materials that can be used without traditional lab infrastructure. In few words, the protein of interest (in this case, 6xHis-sfGFP) is produced in cell-free lysates overnight. The day after, it is purified using NEBExpress Spin Columns and all the centrifugation steps (for binding, washing and elution) are performed using a 3D-printed hand-powered centrifuge. The activity lasts two hours.
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.
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; both teacher heads agree on what is shown here.
