Correlation between Microarray DNA Hybridization Efficiency and the Position of Short Capture Probe on the Target Nucleic Acid
Bibliographic record
Abstract
The hybridization behavior of small oligonucleotides arrayed on glass slides is currently unpredictable. In order to examine the hybridization efficiency of capture probes along target nucleic acid, 20-mer oligonucleotide probes were designed to hybridize at different distances from the 5' end of two overlapping 402- and 432-bp ermB products amplified from the target DNA. These probes were immobilized via their 5' end onto glass slides and hybridized with the two labeled products. Evaluation of the hybridization signal for each probe revealed an inverse correlation with the length of the 5' overhanging end of the captured strand and the hybridization signal intensity. Further experiments demonstrated that this phenomenon is dependent on the reassociation kinetics of the free overhanging tail of the captured DNA strand with its complementary strand. This study delineates key predictable parameters that govern the hybridization efficiency of short capture probes arrayed on glass slides. This should be most useful for designing arrays for detection of PCR products and nucleotide polymorphisms.

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.
