Methods and kits for labeling nucleic acids are provided. In the subject
methods, an oligonucleotide tagged nucleic acid comprising an
oligonucleotide tag is first generated. The oligonucleotide tagged
nucleic acid is then contacted under hybridization conditions with a
labeled oligonucleotide complementary to the oligonucleotide tag,
yielding a labeled nucleic acid. The kits of the subject invention at
least include a primer for use in enzymatically generating an
oligonucleotide tagged target nucleic acid, where the primer generally at
least includes an oligo dT region and the oligonucleotide tag, and a
labeled oligonucleotide complementary to the oligonucleotide tag. The
subject methods and kits find use in a variety of applications, and are
particularly suited for use in gene expression analysis applications.
