Patent number: 9422603Abstract: 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.Type: GrantFiled: February 20, 2015Date of Patent: August 23, 2016Assignee: Applied Biosystems, LLCInventors: Kai Qin Lao, Neil A.
