Event-Specific Qualitative and Quantitative Polymerase Chain Reaction Methods for Detection of Genetically Modified Rapeseed Ms8Rf3 Based on the Right Border Junctions
Bibliographic record
Abstract
Ms8xRf3 is a genetically modified rapeseed hybrid which is widely cultivated in Canada and exported to some other countries for production of foodstuffs or fodder. In this study, the genomic sequences flanking the right borders of the integrated transgenic sequences in the Ms8xRf3 genome were characterized and showed high similarities with the bacterial artificial chromosome clone of Chinese cabbage. Event-specific qualitative polymerase chain reaction (PCR) methods were established with the primers and probes targeting the junction regions to produce a 123 base pair (bp) product for the Ms8 event and 92 bp for the Rf3 event. The absolute detection limit of qualitative PCR was 2.5 initial template copies for the Ms8 event and 50 copies for the Rf3 event. Quantitiative detection methods were established, with the absolute quantification limit being approximately 25 initial template copies.

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.
