Exempel på hur man kan använda ASSAYS i en mening

• Synthetic peptide nucleic acid oligomers have been used in recent years in molecular biology procedures, diagnostic assays, and antisense therapies.
• It is a two-dimensional array on a solid substrate—usually a glass slide or silicon thin-film cell—that assays (tests) large amounts of biological material using high-throughput screening miniaturized, multiplexed and parallel processing and detection methods.
• The history of molecular evolution starts in the early 20th century with comparative biochemistry, and the use of "fingerprinting" methods such as immune assays, gel electrophoresis, and paper chromatography in the 1950s to explore homologous proteins.
• Still, the blood values are approximately equal between the arterial and venous sides for most substances, with the exception of acid–base, blood gases and drugs (used in therapeutic drug monitoring (TDM) assays).
• Biologists use it in cellular assays to detect copper, iron, and cyanides as well as specific proteins via western blotting.
• Burnet's major achievements in microbiology included discovering the causative agents of Q-fever and psittacosis; developing assays for the isolation, culture and detection of influenza virus; describing the recombination of influenza strains; demonstrating that the myxomatosis virus does not cause disease in humans.
• Large-scale drug screening (or urine, hair and other samples) is usually done using enzyme-linked immunosorbent assays (ELISA).
• As natural chemicals turned out to also be frequently mutagenic, he argued that environmental exposure to manufactured chemicals may be of limited relevance to human cancer, even when such chemicals are mutagenic in an Ames test and carcinogenic in rodent assays.
• Common detection modes for microplate assays are absorbance, fluorescence intensity, luminescence, time-resolved fluorescence, and fluorescence polarization.
• Depending on the results of this first assay, the researcher can perform follow up assays within the same screen by "cherrypicking" liquid from the source wells that gave interesting results (known as "hits") into new assay plates, and then re-running the experiment to collect further data on this narrowed set, confirming and refining observations.
• It also has many applications in biotechnologies, typically enzyme assays for biochemistry including biosensors in nanotechnologies.
• Aquatic toxicology tests (assays): toxicity tests are used to provide qualitative and quantitative data on adverse (deleterious) effects on aquatic organisms from a toxicant.
• A cork borer is also used to punch holes on an agar plate and to perform well diffusion assays in microbiology to study bioactivity.
• The assays were made in the cupellation or assay furnace, which needs to have windows and bellows to ascertain that the air oxidises the lead, as well as to be sure and prepared to take away the cupel when the process is complete.
• The extract of dried flowers showed neuroprotective, free-radical scavenging, antioxidative effects in in vitro assays.
• There are also possibly rarer subtypes, the translocases for inorganic phosphate (GSD Ic) or glucose (GSD Id); however, a recent study suggests that the biochemical assays used to differentiate GSD Ic and GSD Id from GSD Ib are not reliable, and are therefore GSD Ib.
• The presence of neurotransmitters (though not necessarily the location) can be observed in enzyme-linked immunocytochemistry or enzyme-linked immunosorbent assays (ELISA) in which substrate-binding in the enzymatic assays can induce precipitates, fluorophores, or chemiluminescence.
• Gamma counters are used in radiobinding assays, radioimmunoassays (RIA) and nuclear medicine measurements such as GFR and hematocrit.
• Although Wood's copper coins were subsequently alleged to be underweight, undersized, and made from inferior materials, assays had found they were not so, prior to their approval by the Parliament of Great Britain for use in Ireland.
• Through the use of immunofluorescence studies, live cell imaging, gel mobility shift assays, and bimolecular fluorescence complementation, the above was determined and also by comparing the chromatin binding properties of wild-type and HMGN mutant proteins.
