Competitive immunoassay for vancomycin using capillary electrophoresis with laser-induced fluorescence detection
Bibliographic record
Abstract
A competitive immunoassay using capillary electrophoresis with laser-induced fluorescence was developed for vancomycin. Capillary electrophoresis using a Tris-glycine running buffer provided adequate separation of the antibody-bound from the unbound fluorescent probe (tracer) in less than 4 min. Laser-induced fluorescence polarization (LIFP) provided high sensitivity detection and simultaneous monitoring of fluorescence intensity and polarization. A fluorescence polarization value of 0.30 confirmed the formation of the antibody-tracer complex. Calibration curves showed a working linear range of 2-3 orders of magnitude with a minimum detectable concentration of 0.98 ng mL(-1) (or 1.1 fg vancomycin). Clinical samples obtained from patients undergoing vancomycin treatment were analyzed for vancomycin and the results correlated well with a standard immunoassay based on latex particle detection that was routinely used by a hospital laboratory. Only 1/10 of the reagents were needed as compared with the standard immunoassay.

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.
