摘要: The present disclosure relates to the amplification of target nucleic acid sequences for various sequencing and/or identification techniques. This can be accomplished via the use of target primers and isothermal multiple strand displacement (MDA) processes. The use of these target primers and MDA, as described herein, allows for, for example, the reduction in the amplification of undesired hybridization events (such as primer dimerization and the “jackpot mutation” effect of PCR) while allowing for the amplification of the target nucleic acid sequences.

摘要: The present teachings provide methods for amplifying a plurality of target nucleic acids. In some embodiments, a first oligo-dT-universal primer comprising a 3′ oligo-dT portion and a first 5′ universal portion is used to reverse transcribe a plurality of 3′ poly-A tail-containing nucleic acids. A poly-A tail is added to the 3′ end of the first strand products to form a two-tailed reaction product. The two-tailed reaction product is amplified in a PCR, wherein the PCR comprises the first oligo-dT-universal primer, and a second oligo-dT-universal primer, wherein the second oligo-dT-universal primer comprises a 3′ oligo-dT portion and a second 5′ universal portion, wherein the second 5′ universal portion of the second oligo-dT-universal primer comprises a different sequence than the first 5′ universal portion of the first oligo-dT-universal primer. The present teachings also provide compositions and kits for amplifying target nucleic acids containing monomorphic tails.
