一般說明

麦胚 tRNA 含有许多不同的特异性 tRNA 分子。

應用

粗转移 RNA (tRNA) 从小麦胚芽中提纯,含有许多特定的 tRNA 分子,可以通过不同的过程分离。利用 体外 翻译系统进行详细的结构和功能研究实验通常需要高纯度的 tRNA,这可以通过色谱分离和 tRNA 的可逆生化修饰的组合来实现。麦胚 tRNA 已用于从麦胚纯化 RNAse Z(tRNA 3′-处理核酸内切酶)。纯化包括 6 个步骤,其中最有效的步骤是使用由麦胚 tRNA 构成的亲和柱,其与 RNAse Z 紧密结合。
适合作为核酸纯化和沉淀中的载体使用。

成分

tRNA 以冻干粉形式提供,可溶于水,浓度为 2 mg/mL。

Post-translational modification of histone tails is thought to modulate higher-order chromatin structure. Combinations of modifications including acetylation, phosphorylation and methylation have been proposed to provide marks recognized by specific proteins. This is exemplified, in both mammalian cells and fission yeast
