USE OF DESTABILIZING NUCLEOTIDE TRIPHOSPHATES TO REDUCE AMPLICON FOLDING AND Tm

Granted: October 10, 2024
Application Number: 20240336961
Described herein are methods and compositions that provide highly efficient primer annealing and denaturation during nucleic acid amplification. The basic method employs destabilizing nucleotide triphosphates (dNTPs) in amplification reaction mixtures. The incorporation of such dNTPs into the amplicon produced upon amplification lowers the Tm of the amplicon, promoting denaturation/strand separation for the next round of primer annealing.

EXPONENTIAL BASE-GREATER-THAN-BASE 2 NUCLEIC ACID AMPLIFICATION USING HIGH- AND LOW-Tm PRIMERS

Granted: March 28, 2024
Application Number: 20240102085
Described herein are methods and compositions that provide highly efficient nucleic acid amplification. The method employs pairs of primers that differ significantly in Tm and a novel temperature/time course characterized by a temperature pulse during denaturation that enables a high-Tm primer (but not a low-Tm primer) to anneal and prime the synthesis of an additional nucleic acid strand beyond the two strands synthesized in a cycle of classical PCR. In some embodiments, this allows a…
