Abstract: The present disclosure relates to the amplification of target nucleic acid sequences. This can be accomplished via the use of various primers. The use of these primers, as described herein, results in nucleic acid structures that can reduce the amplification of nonspecific hybridization events (such as primer dimerization) while allowing the amplification of the target nucleic acid sequences.

Abstract: The present teachings provide methods, compositions, and kits for performing primer extension reactions on at least two target polynucleotides in the same reaction mixture. In some embodiments, a reverse transcription reaction is performed on a first target polynucleotide with a hot start primer comprising a self-complementary stem and a loop, and extension products form at high temperatures but extension products form less so at low temperatures since the self-complementary stem of the hot start primer prevents hybridization of the target specific region to the target. However, non-hot start primers with free target specific regions can hybridize to their corresponding targets at the low temperature and extension can happen at the low temperature.
