An antigen-capture enzyme-linked immunosorbent assay (ELISA) to detect isometamidium chloride in Oncorhynchus spp.
Bibliographic record
Abstract
An antigen-capture enzyme-linked immunosorbent assay (ELISA) was developed to detect and measure isometamidium chloride in the plasma of Oncorhynchus tshawytscha and O. mykiss. Isometamidium-ovalbumin conjugate and anti-isometamidium antibodies were used to coat polystyrene plates. The peroxidase saturation technique was used to optimize the coating antigen concentration; it demonstrated low affinity of the isometamidium-ovalbumin conjugate but high affinity of the anti-isometamidium antibodies for polystyrene surface sites. The optimal conditions of antiisometamidium antibodies to coat plates was at pH 7.3 and a 1:1000 dilution (0.0012 mg ml(-1) protein). The ELISA was sensitive as it detected 0.0006 mg ml(-1) of isometamidium in fish plasma. Isometamidium diluted with saline could not be detected at concentrations less than 0.05 mg ml(-1). The results indicate that this ELISA is much more sensitive when isometamidium is bound to plasma than unbound isometamidium in saline.

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.
