Advances in nanobody multimerization and multispecificity: from <i>in vivo</i> assembly to <i>in vitro</i> production
Bibliographic record
Abstract
NANOBODIES® (Nbs) have emerged as valuable tools across therapeutic, diagnostic, and industrial applications owing to their small size and consequent ability to bind unique epitopes inaccessible to conventional antibodies. While Nbs retrieved from immune libraries normally possess sufficient affinity and specificity for their cognate antigens in the practical use case, their multimerization will often increase functional affinity via avidity effects. Therefore, to rescue binding affinity and broaden targeting specificities, recent efforts have focused on conjugating multiple Nb clones - of identical or unique antigen cognates - together. In vivo and in vitro approaches, including flexible linkers, antibody domains, self-assembling coiled coils, chemical conjugation, and self-clustering hydrophobic sequences, have been employed to produce multivalent and multispecific Nb constructs. Examples of successful Nb multimerization are diverse, ranging from immunoassaying reagents to virus-neutralizing moieties. This review aims to recapitulate the in vivo and in vitro modalities to produce multivalent and multispecific Nbs while highlighting the applications, advantages, and drawbacks tied to each method.

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; a candidate call from one teacher head, not a consensus.
