Researchers have published a new technique for the rapid and accurate identification of fentanyl, as well as a vast number of other drugs of abuse.
Browsing: MS (LC–MS/MS, HRMS, IMS)
We talk to Zheng Oyang about his career, emerging technologies and miniature mass spectrometry as a focus for his recent work.
Post-acquisition data mining techniques for LC–MS/MS-acquired data in drug metabolite identification
This review discusses the targeted and untargeted post-acquisition data mining techniques, which facilitate the drug metabolite identification. Learn more in this article from Bioanalysis.
Development of Native and Denaturing LC-MS Methods for Characterization of Cysteine-Linked Antibody Drug Conjugates Using a Non-Toxic Mimic
Here we utilize a cysteine-linked antibody fluorophore conjugate to show how LC-MS methods may be optimized using a non-toxic ADC-mimic. The ADC-mimic was used to develop native and reduced SEC-MS conditions. The reduced mimic’s heavy and light chains, as well as its IdeS-proteolysis fragments, were used to develop reversed-phase LC-MS methods. A tryptic digest of the ADC mimic was used to develop a peptide mapping LC-MS method.
