transcript expression assay nucleic acid dot/slot blot assay 2018-05-28T18:08:59Z A method that assesses transcript expression in which unfracionated RNA is covalently bound to a membrane and subsequently analysed by hybridization to one or more specific probes that have been labelled to allow detection, or DNA sequences of interest are bound to a membrane and hybridized to a labelled RNA/cDNA sample. Visualization of the sequence-specific binding of labelled molecules to target(s) gives an indication of the amount of the sequence of interest in the original sample.
