The MIQE Guidelines: Minimum Information for Publication of Quantitative Real-Time PCR Experiments
Open accessAbstract
Background: Currently, a lack of consensus exists on how best to perform and interpret quantitative real-time PCR (qPCR) experiments. The problem is exacerbated by a lack of sufficient experimental detail in many publications, which impedes a reader’s ability to evaluate critically the quality of the results presented or to repeat the experiments. Content: The Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines target the reliability of results to help ensure the integrity of the scientific literature, promote consistency between laboratories, and increase experimental transparency. MIQE is a set of guidelines that describe the minimum information necessary for evaluating qPCR experiments. Included is a checklist to accompany the initial submission of a manuscript to the publisher. By providing all relevant experimental conditions and assay characteristics, reviewers can assess the validity of the protocols used. Full disclosure of all reagents, sequences, and analysis methods is necessary to enable other investigators to reproduce results. MIQE details should be published either in abbreviated form or as an online supplement. Summary: Following these guidelines will encourage better experimental practice, allowing more reliable and unequivocal interpretation of qPCR results.

“If multiple reactions are performed, however, accurate quantification of lower concentrations can be obtained via digital PCR (29,63,64 )”

The Results section explains that digital PCR partitions a sample into hundreds of reaction chambers. At low target concentrations, counting positive chambers closely approximates the true concentration, supporting the claim that multiple reactions enable accurate quantification at lower concentrations. (LLM, conf=0.92)
- Supportedcites [64] 1999, Proc Natl Acad Sci U S A source
The Discussion (page not provided) says digital PCR can detect mutations at relatively low levels and that its detection limit depends on the number of wells analyzed. It also describes quantitative analysis of PCR products, supporting the claim that multiple reactions enable quantification at low levels; the paper’s example concerns rare variants within a sample.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
