conserved signal molecules that mediate quorum sensing in Gram-negative bacteria. In this study, deuterium-labeled AHLs were prepared for use as internal standards for isotope dilution mass spectrometry. Their utility in the sensitive and precise quantification of AHLs in culture supernatants of bacteria by GC/MS was demonstrated.
N-酰基高
丝氨酸内酯(AHL)是广泛保守的信号分子,可介导革兰氏阴性细菌的群体感应。在这项研究中,制备了
氘标记的AHL,用作同位素稀释质谱法的内标。证明了它们在通过GC / MS对细菌培养物上清液中AHL进行灵敏而精确的定量分析中的效用。
