synthesized charged chiral tag-enabled enantioselective imaging of D-,L-2-hydroxyglutaric acid, which are independently associated with the regulation of DNA methylation. The tag-conjugated diastereomers were ionized efficiently through MALDI, separated by ion mobility spectrometry, and further separated from other molecules in mass spectrometry. On-tissue chiral derivatization using the tag facilitated
新合成的带电手性标签可对D -, L -2-羟基戊二酸进行对映选择性成像,其与 DNA 甲基化的调节独立相关。标签缀合的非对映异构体通过 MALDI 有效电离,通过离子迁移谱分离,并在质谱中进一步与其他分子分离。使用该标签进行的组织手性衍生化有助于观察小鼠睾丸中两种异构体的不同分布。
