unknown bioactive molecules produced by gut microbiota in the human host. Herein, we utilize a chemoselective probe immobilized to magnetic beads for analysis of carbonyls in human fecal samples. We identified 112 metabolites due to femtomole analysis and an increased mass spectrometric sensitivity by up to six orders of magnitude.
需要新的策略来发现人类宿主中肠道菌群产生的未知生物活性分子。在本文中,我们利用固定在磁珠上的化学选择性探针来分析人粪便样品中的羰基。我们鉴定了112种代谢物,这是由于其具有飞摩尔分子的分析能力,并且质谱灵敏度提高了多达六个数量级。
