说明

一般描述

Formamide, a naturally occurring amide, contains carbon, hydrogen, oxygen, and nitrogen in its structure.
 

应用

Formamide has been used:
  • as a component in the hybridization buffer for in situ hybridization as a component of solution X to wash the slides to remove the coverslips
  • in the preparation of denaturation solution for spectral karyotyping (SKY) analysis
  • in the preparation of 1% formaldehyde solution for the pretreatment of slides for comparative genomic hybridization (CGH)
  • to prepare pre-hybridization buffer I, II, III, IV, and hybridization buffer I, II, and III for RNA fluorescence in situ hybridization (RNA-FISH)
  • as an ionizing solvent in the production of formic esters and vitamin, a softener for paper, in animal glues, and water-soluble gums, in molecular biology as a denaturing agent
甲酰胺可使核酸双螺旋不稳定，通常可以 50% 的浓度，用于需要较低杂交温度的杂交实验。
 

生化/生理作用

Formamide serves as a good solvent for polar organic and inorganic compounds with potential catalytic activity in prebiotic processes due to its high dielectric constant.
