Descrição geral

Formamide is a clear liquid amide derived from formic acid. Formamide allows for the denaturation and renaturation of nucleic acids at room temperature.


Formamide is suitable for use in hybridization buffers made using standard recipes. Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.

Other applications include:

  • Preparation of brain sections of mice for BrdU immunohistochemistry
  • FISH analysis of HeLa cells.
  • Preparation of the polyacrylamide gel for analysis of PCR products using denaturing gradient gel electrophoresis(The Merck Index, 12th ed).
Formamide destabilizes nucleic acid duplexes and may be used, typically, at a concentration of 50%, in hybridization protocols requiring lower hybridization temperatures.
