Abstract
Glycosylation is the most prevalent form of posttranslational modification of recombinant glycoproteins. N-linked glycans are added to protein as a co-translational modification in the endoplasmic reticulum (ER). Recombinant proteins may also contain O-linked glycans attached through an N-acetylgalactosamine residue that are structurally different than N-linked glycans, but include many of the same monosaccharides and linkages. A very important example of how structure is important in function is the glycosylation of monoclonal antibodies (IgG). Modification of glycan structure can also be accomplished through the addition of glycoprotein-processing inhibitors to the culture media during production. The development and refinement of glycan structural analysis has been a key asset in defining the relationship between glycoprotein structure and function of biopharmaceuticals. Fluorophore-assisted Carbohydrate Electrophoresis (FACE) is an older method that separates and quantifies glycans based on their size using high-density gels. Quantitative analysis of glycosylation by mass spectrometry has also made considerable advances in recent years.

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.
