1,2] This technique, which is both highly sensitive and specific, uses a DNA probe specific for a chromosome or chromosomal region labeled with nonradioactive
fluorescent molecules that are then hybridized to the homologous regions in cells.
It's really a nonradioactive
tracer method that follows the PCR reaction quantitatively, and focuses only on the desired DNA segment and not on any DNA impurities that could start to amplify as well, says Bard.
However, a filter at the facility became clogged with nonradioactive
material in June.
We developed a nonradioactive
assay to measure thyroid-stimulating immunoglobulins (TSIs).
The rest of the patients, the study's control group, received a similar but nonradioactive
It may include the use of biological agents, such as bacteria, algae, or fungi, or their biochemical byproducts, to degrade hazardous, nonradioactive
wastes to the point where they either are no longer hazardous, or at least are much less hazardous to the environment.
In their experiments, the researchers used nonradioactive
strontium, which is chemically identical to the radioactive version.
Etiologic researchers have moved away from RIA in favor of nonradioactive
immunoassays, and in some cases higher sensitivity mass spectrometry-based assays, for measuring serum testosterone concentrations.
At sites across the United States, hundreds of concrete, steel-lined tanks hold toxic mixes of radioactive metals and nonradioactive
compounds--organic and inorganic--left over from production of nuclear weapons.
If nuclear irradiation can create unstable isotopes, then, by all means, why can't selectively irradiated isotopes be rendered stable and nonradioactive
