Competitive Affinity Release for Long‐Term Delivery of Antibodies from Hydrogels
Bibliographic record
Abstract
With increased clinical use of antibodies, long-term delivery strategies are needed to decrease injection frequency and improve health outcomes. A three-component drug-delivery system was developed for competitive affinity release of a streptavidin-antibody conjugate from agarose-desthiobiotin hydrogels via controlled dissolution of sparingly soluble biotin derivatives. The antibody conjugate was localized in the hydrogel through streptavidin-desthiobiotin complexation. Dissolution of sparingly soluble biotin derivatives disrupts streptavidin-desthiobiotin complexation for controlled release of the antibody conjugate. Release was tuned by altering the total biotin derivative concentration without further hydrogel or antibody modification. First-order tunable release of bioactive Avastin, a therapeutic anti-VEGF antibody, was demonstrated from a non-cytotoxic system for over 100 days.

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.
