US Patent 7993839 Methods and kits for reducing non-specific nucleic acid amplification

Methods and kits for efficient amplification of nucleic acids are provided. The methods comprise in-vitro amplification of a nucleic acid template employing partially constrained primers having terminal mismatch primer-dimer structure. The methods also comprise in-vitro amplification of a nucleic acid template employing partially constrained primers having nucleotide analogues. The methods enhance efficiency of nucleic acid amplification reaction by reducing non-specific amplification reactions.
