Accelerated isothermal nucleic acid amplification in betaine-free reaction.

Betaine was used as a common additive to isothermal nucleic acid amplification reactions because of lowering the melting temperature (Tm) of DNA. Herein, we reported a novel finding that betaine was inhibiting the reaction efficiency of isothermal amplification reactions. In this work, we have verified this finding by classical loop-mediated isothermal… CONTINUE READING
