2. A device or agent used to detect or explore a substance, e.g., a molecule used to detect the presence of a specific fragment of DNA or RNA or of a specific bacterial colony. 3. To enter and explore, as with a probe.
DNA sequences or RNA transcripts that have moderate to high sequence similarity to the probe are then detected by visualizing the hybridized probe via autoradiography or other imaging techniques. Normally, either X-ray pictures are taken of the filter, or the filter is placed under UV light.ybridization probes used in DNA microarrays refer to DNA covalently attached to an inert surface, such as coated glass slides or gene chips, to which a mobile cDNA target is hybridized.
