설명

일반 설명

Formamide is a colorless organic solvent. It has been reported to increase the precision of PCR (Polymerase Chain Reaction) studies. Microwave spectral study of its isotopic forms suggests that the molecule of formamide is nonplanar in which the H₂N-C group exhibits a shallow pyramid like structure.

애플리케이션

Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.
