The phrase "assay principle" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing the fundamental concepts or methods behind an assay.
Example: "The assay principle involves measuring the concentration of a substance by observing its reaction with a specific reagent."
Alternatives: "testing principle" or "analysis principle".
Routine use will establish which assay principle and which parameters best serve the intended purpose.
The assay principle is based on the determination of the oxygen consumption rate caused by microbial respiration.
A homogeneous non-competitive assay principle for measurement of small analytes based on quenching of fluorescence is described.
The assay principle is based on staining of a drop (1 µl) analyte on a nitrocellulose membrane strip by using silica/gold nanoshells conjugated with biospecific probing molecules.
The assay principle is based on the ability of bona fide inflammatory agents to activate the transcription factor NF-κB in cultured cells.
The assay principle of the pectic substances is based on the colorimetric determination of the galacturonic acid content of the pectic chains hydrolyzed in hot acidic medium of different fractions isolated in the presence of 3-hydroxydiphenyl [21].
Several platforms are available offering different assay principles and read-out parameters: patch-clamp and field potential recording, imaging or photometry, impedance measurement, and recording of contractile force.
Several assay principles have been described.
Regardless of the assay principles, these methods share the common feature that a pair of oligonucleotide probes is designed to cover and flank the SNP.
