应用
Formamide is used for cryopreservation of tissues and organs and in hybridization buffers. It acts as an RNA stabiliser in gel electrophoresis by deionizing RNA. It is used as an alternative solvent for the electrostatic self-assembly of polymer nanofilms. It is used in the preparation of brain sections of mice for BrdU immunohistochemistry and fish analysis of HeLa cells. It essentially plays a vital role in crystallization of pharmaceuticals, in soil stabilization, as a solvent in inks, as a component of liquid fertilizers, as a heat-resistant coatings and in some personal care products. 备注

产品说明 一般描述 甲酰胺是一种衍生自甲酸的透明液体酰胺。甲酰胺可让核酸在室温下变性和复性。 应用 甲酰胺适用于使用标准配方配制的杂交缓冲液。甲酰胺可弱化核酸双链体稳定性，通常在需要较低杂交温度的杂交方案中50％浓度使用。
其他应用包括：
- 制备用于BrdU免疫组化的小鼠脑切片
- HeLa细胞FISH分析。
- 使用变性梯度凝胶电泳法制备用于PCR产物分析的聚丙烯酰胺凝胶(《The Merck Index》第12版)。
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。 特点和优势 - 分子生物学应用去离子
- 封装在氩气填充的棕色瓶中，以防氧化
- 用于DNA复性或DNA-RNA杂交
- 可降低双链核酸的热稳定性
适用性 - 核酸杂交
- 防冻剂和凝胶稳定剂
- 弱化核酸双链体稳定性
- 消除核酸二级结构
- 制备RNA和DNA应用所需的杂交缓冲液
