一般描述

甲醛是一种分子生物学试剂,当掺入琼脂糖凝胶时,在电泳过程中使RNA变性。
它是一种脂肪族醛,在工业上广泛用于合成几种化学品,如三聚氰胺甲醛、脲醛、酚甲醛和工业树脂、多聚甲醛、多元醇、螯合剂、缓释肥料、1,4-丁二醇和六亚甲基四胺。

应用

甲醛溶液适用于:
  • RNA分子的变性和分离
  • 抗菌治疗
  • 细胞固定
甲醛溶液已被用于:
  • 人精原干细胞移植(SSCT)的固定。
  • 在染色质免疫沉淀过程中交联T细胞急性淋巴细胞白血病蛋白/DNA复合体。
  • 斑马鱼幼体中性粒细胞染色固定。

注意

可能含有沉淀(多聚甲醛)

原理

甲醛能够破坏RNA的二级结构,并帮助实现基于电荷迁移的RNA种类分离和鉴定。

Epstein-Barr virus (EBV) causes human lymphoid malignancies, and the EBV product latent membrane protein 1 (LMP1) has been identified as an oncogene in epithelial carcinomas such as nasopharyngeal carcinoma (NPC).

The production of ribosomes is ubiquitous and fundamental to life. As such, it is surprising that defects in ribosome biogenesis underlie a growing number of symptomatically distinct inherited disorders, collectively called ribosomopathies.
