  • Publication number: 20130029881
    Abstract: Methods are provided for adding a terminal sequence tag to nucleic acid molecules for use in RNA or DNA amplification. The tag introduced may be used as a primer binding site for subsequent amplification of the DNA molecule and/or sequencing of the DNA molecule and therefore provides means for identification and cloning of the 5?-end or the complete sequence of mRNAs.

  • Patent number: 6498024
    Abstract: A kit is provided for preferentially amplifying target RNA in a sample of tester RNA relative to non-target RNA in the sample, the kit driver sequences complementary to the non-target tester RNA under conditions where the driver sequences hybridize to the non-target RNA, a nucleic acid primer capable of hybridizing to the target RNA under conditions suitable for extension of the nucleic acid primer; and a promoter template capable of hybridizing to a DNA that is complementary to the target RNA under conditions suitable for extension of the complementary DNA such that a functional double promoter is formed.

  • Patent number: 5712127
    Abstract: A method is provided for preferentially amplifying target RNA relative to non-target RNA in a sample of tester RNA. According to the method, a sample of tester RNA is contacted with driver sequences which are complementary to the non-target RNA under conditions where the driver sequences hybridize to the non-target RNA. A nucleic acid primer is then extended using the target RNA as a template, forming a DNA template complementary to some or all of the target RNA. The DNA template formed using the target RNA as template is then rendered single-stranded to enable the hybridization of the DNA template to a promoter template. The DNA template is then extended using the promoter template to form an extended DNA template comprising a functional double-stranded promoter. Multiple copies of the target RNA sequence can now be transcribed from the extended DNA template through recognition of the contained functional double-stranded promoter by RNA polymerase.
