We describe a novel methylation-sensitive nucleic acid (RNA) probe which switches conformation according to its methylation status. When combined with a differential scanning fluorimetry technique, it enables highly sensitive and selective detection of demethylase activity at a single methylated-base level. The approach is highly versatile and may be adapted to a broad range of RNA demethylases.
我们描述了一种新型的甲基化敏感核酸(RNA)探针,它根据其甲基化状态改变构象。当与差示扫描荧光技术结合使用时,它能够在单个甲基化碱基水平上实现高度敏感和选择性的脱甲基酶活性检测。该方法具有高度的通用性,可适用于广泛的 RNA 脱甲基酶。
