The phrase "amount assay" is not commonly used in written English and may not be correct depending on the intended meaning.
It could be used in contexts related to scientific or analytical measurements, particularly in fields like chemistry or pharmaceuticals, where "assay" refers to testing or analysis.
Example: "The amount assay revealed a significant concentration of the active ingredient in the sample."
Alternatives: "quantity analysis" or "measurement assay."
Cell extracts were diluted 1 10 in increasing amounts (assay end concentration ranging from 33.75 nM to 3.375 mM) of the iron chelator phenanthroline in an optimized buffer containing 50 mM triethanolamine/HCl (pH 7.5), 150 mM NaCl, 10% (v/v) glycerol, 10 mM ascorbic acid and 20 μM tetrahydrobiopterin.
Without PCR the total assay time amounts to 27 min.
with copy numbers for each transcript per sample determined based on the EC50 of standard curve titrations of known competitor amounts per assay vs. a fixed amount of cDNA template.
In addition, data indicates a positive correlation between the predictive in silico specificity score and the amount of assay non-specific coverage.
Although saliva collection and determination present some disadvantages, it has been recognised as an attractive diagnostic fluid with an increasing amount of assay developments and technological advancements for the detection of various salivary biomarkers.
After sterilization, equal amounts of assay medium (20 mL) were poured in sterilized petri dishes (12 cm in diameter).
Performing a large amount of assays concurrently on one sensor surface offers a clear solution to problems of variability [3].
The maximal velocity of an enzyme (Vmax) is proportional to protein amount when assayed under optimal conditions.
However, it is not certain that further increasing amounts of assay data will indeed significantly alter the currently emerging view of compound promiscuity (vide infra).
Unfortunately, results of bacterial sampling are often falsely negative, be it due to inadequately low amounts material, assay insensitivity or prior antibiotic use, to name just a few.
