The phrase "assay of what" is not correct and does not convey a clear meaning in written English.
It may be used in contexts where one is questioning the subject or purpose of an assay, but it lacks clarity without additional context.
Example: "In the study, we need to clarify the assay of what specific compounds we are testing."
Alternatives: "analysis of what" or "evaluation of what".
For the interpretation of negative results, understanding the limit of detection of the sequencing assay (at what allele frequency can the variant be detected by the assay) is important, and requires specific knowledge of the tumor content of the sample.
It remains, however, a very expensive assay to perform, prompting the development of what could be called 'survey' assays that test a subset of the cytosines dispersed throughout the genome.
Four different amplicon sizes are amplified in parallel in a single tube from cDNA (multiplexed endpoint RT-PCR assay) to minimise the consumption of what are often limited amounts of RNA.
Using this microsomal activation mixture, Malling (1971) showed that dimethylnitrosamine was mutagenic in Salmonella in a liquid-suspension assay, resulting in the first version of what would later be called the Salmonella/mammalian microsome mutagenicity assay.
It was a powerful tool to take a gross empirical assay to give a biochemical idea of what's going on.
It would also be important to provide a clear definition of what is being phenotypically assayed.
What sets the Tiered Protocol for Endocrine Disruption (TiPED) apart from the protocols typically used to assess product safety is its incorporation of what the authors believe to be the best assays for detecting effects on the endocrine system.
As these examples illustrate, a clear understanding of what forms are being measured is essential for the assessment of assay bias and for meaningful result interpretation.
Standardization requires knowledge of what is released after cardiac injury and what the various cardiac troponin assays are measuring.
Although the development of a quantitative assay what not an initial goal of this work, and outside the scope of the work presented here, this feature contributed to its selection as a target for this work.
In conclusion, this retrospective study shows that despite the unresolved controversies regarding diagnosis, the relevance of interferon gamma assays and what exactly ocular tuberculosis is, if patients have a consistent uveitis phenotype and other uveitic causes are excluded, then ATT is likely to have a beneficial effect.
