A nuclear stress test is one of several types of stress tests that may be performed alone or in combination. Compared with an exercise stress test, a nuclear stress test can help better determine your risk of a heart attack or other cardiac event if your doctor knows or suspects that you have coronary artery disease.
DNA microarray analysis is one of the fastest-growing new technologies in the field of genetic research. Scientists are using DNA microarrays to investigate everything from cancer to pest control. Now you can do your own DNA microarray experiment!
DNA microarray. In spotted microarrays ,the probes are oligonucleotides, cDNA, or small fragments of PCR products that correspond to mRNAs.Each probe contains a different, characteristic sequence that is specific to a different group of genes under study.These probes are then spotted onto glass substrate to form an array.n oligonucleotide microarrays, the probes are short sequences designed to match parts of the sequence of known or predicted open reading frames. Although oligonucleotide probes are often used in spotted microarrays, the term oligonucleotide array most often refers to a specific technique.
