應用
溴化乙锭 (EtBr) 是 PAGE 或琼脂糖凝胶电泳最常用的核酸染色剂。EtBr 的荧光在与双链 RNA 结合后可增加 21 倍，在与双链 DNA 结合后增加 25 倍，因此在低染色浓度（10μg/ml）下无需本底脱色。溴化乙锭已用于大量核酸荧光测定。 它已被证明可与单链 DNA（虽然没有那么强）和三链 DNA 结合。由于它能与 DNA 结合，EtBr 是 DNA 聚合酶的抑制剂。
插入双链 DNA 和 RNA 的移码诱变剂。
插入双链 DNA 和 RNA 的移码诱变剂。
生化／生理作用
溴化乙啶可插入双链 DNA 和 RNA 中，并作为移码诱变剂。它还可与吖啶橙结合用于区分存活的、凋亡的和坏死的细胞。
重構
对于在电泳后进行凝胶染色，应先用水将储存液样品稀释到 0.5μg/ml，再将凝胶孵育 15-30 分钟。通常无需脱色，但是如果必须降低背景色，则可在水中脱色 15 分钟。然后可在紫外灯箱（254nm 波长）中检测 DNA 条带。也可将溴化乙啶加到凝胶和电泳缓冲液（终浓度 0.5μg/ml）中，并在电泳后立即显影。

Regenerative medicine requires the use of heterogeneous scaffolds when the tissue that needs to be repaired presents a gradient in its properties and cannot be replaced by a homogeneous graft. Then, an intimate contact between the different layers is critical

Alternative splicing (AS) of precursor RNAs is responsible for greatly expanding the regulatory and functional capacity of eukaryotic genomes. Of the different classes of AS, intron retention (IR) is the least well understood. In plants and unicellular eukaryotes, IR is

The DNA uptake of naturally competent bacteria has been attributed to the action of DNA uptake machineries resembling type IV pilus complexes. However, the protein(s) for pulling the DNA across the outer membrane of Gram-negative bacteria remain speculative. Here we
