Methods are provided for labeling nucleic acid molecules for use in hybridization reactions, and kits employing these methods. The level of labeling is increased by including one or more reactive modifications, such as amine-modifications, into the primers used to initiate synthesis of the nucleic acid molecule, for instance through random-primed reverse transcription. Also provided are modified random primers (such as amine-modified random primers) useful in these methods, labeling and hybridization kits comprising such primers, labeled nucleic acid molecules and mixtures of molecules, and methods for using them. Methods are also provided for amplifying a nucleic acid template contained within extremely small samples, in some cases as little as one cell. In particular embodiments, a single random primer is used for all steps of the amplification method. The nucleic acid template can either be of cellular or viral origin.
A method of producing a modified nucleic acid probe, comprising:
A method of producing a fluorescent hybridization probe, comprising:
An improved method for random primer reverse transcription labeling of a nucleic acid hybridization probe, the improvement comprising using random primers modified with at least one amine-substituted dNTP or fluorescent-dye modified dNTP in the reverse transcription reaction.
A method of producing an RNA template from a small number of cells, comprising:
A method of amplifying a nucleic acid template, comprising:
