The phrase "assay timing" is correct and usable in written English.
It can be used in contexts related to scientific experiments, particularly in reference to the timing of assays or tests conducted to measure the presence or concentration of substances.
Example: "The assay timing is critical to ensure accurate results in the experiment."
Alternatives: "test timing" or "analysis timing".
From these assays, timing and volume data, it was possible to estimate total daily melatonin production and the parameters of the circadian rhythm of melatonin excretion.
We used mγ-LacZ, Miranda, and EdU incorporation to assay the timing of NB3-3T quinscence in wild type and prospero mutant embryos.
To assay the timing of destruction we set up a live-cell assay in which we linked wild type or mutant human cyclin B1 to a fluorescent protein (CFP or YFP) to enable us to compare their destruction in the same cell (in all cases we checked that the same results were obtained when we swapped the fluorescent tags).
Supporting this hypothesis, a developmental timing assay, making use of the different maturation times for green fluorescent protein and red fluorescent protein, demonstrated that during mid- to late somite stages there is continuous cardiogenic differentiation in the ALPM.
The elements of interest (Ca, Mg) were assayed using different timing parameters, namely the irradiation time (t i), the decay time (t d) and the counting time (t c).
To do so, we applied the developmental timing assay, which consists of two fluorescent reporters, EGFP and DsRed, both expressed under the insulin promoter.
The developmental timing assay showed that pharmacological inhibition of Notch- or Nf-kB signaling (using LY411575 and ethyl pyruvate (EP), respectively) enhanced the number of de novo beta-cells, as compared to controls in the anterior half of the primary islet but not the posterior (Supplementary Fig. 15).
Additionally, discussions on study design, critical windows, and new guideline approaches and experiences identified important factors to consider before initiating DIT evaluations including assay choice and timing and the impact of existing adult data.
Note that, this FISH-based assay of replication timing involves stringent cell fixation and denaturation conditions that disrupt nuclear structures, thereby minimizing the contribution of sister chromatid cohesion.
Using FISH mapping and DNA replication timing assay, we found that a large centromeric portion of Z chromosome, comprising a majority of the chromosome, was inverted during evolution.
The characterization of Eptim and Epper enabled us not only to establish a molecular assay of circadian timing, the rhythm of Eptim mRNA expression, but also develop RNAi of Epper as an experimental manipulation.
