Construction of multimerized scFv that neutralize Bovine Herpes Virus-1 (52.12)
Bibliographic record
Abstract
Abstract Our laboratory earlier constructed functional antibody fragments, scFv (single chain fragment variable), with an 18 amino acid linker, against bovine herpes virus-1 (BoHV-1) (Koti et al. 2010. Molec. Immunol. in press). With an objective to enhance scFv avidity, the scFv in Vl-linker-VH configuration was constructed with a short flexible amino acid linker. An overlap PCR product comprising Vl-linker-VH was cloned into pPICZα vector and expressed in Pichia pastoris, under the influence of inducible AOX1 promoter. Affinity purified scFvs were analyzed by Western blot and mass spectrometry that confirmed the expected molecular weight of the scFv. Further, the multimerized scFvs, both purified and unpurified, neutralized BoHV-1 infection of MDBK cells in vitro. Taken together with previous studies, the scFvs with varying linker size are capable of effectively neutralizing BoHV-1. The scFv against BoHV-1 will provide protection at respriratory mucosal surfaces and prevent infection. In conclusion, scFvs both in multimerized and non-multimerized form provide a useful diagnostic and therapeutic agent against an important cattle pathogen. (Supported by NSERC Canada)

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.
