Development of a native nanoelectrospray mass spectrometry method for determination of the drug-to-antibody ratio of antibody-drug conjugates.
TLDR
This novel native nano-ESI MS method in combination with limited enzymatic digestion provides a sensitive method for direct DAR determination and possesses great potential in studying low-abundance ADC analytes such as those from animal or human in vivo investigations. Expand
Quantitative analysis combined with chromatographic fingerprint for comprehensive evaluation of Danhong injection using HPLC-DAD.
A simple, reliable method for simultaneous determination of the ten components in Danhong injection (DHI) in combination of chromatographic fingerprint analysis was developed by high performanceExpand
Simultaneous determination of four alkaloids in Lindera aggregata by ultra-high-pressure liquid chromatography-tandem mass spectrometry.
TLDR
The results indicated that ultra-high-pressure liquid Chromatography-tandem mass spectrometry provided improved chromatographic parameters resulting in significantly increased sample throughput including lower solvent consumption and lower limits of quantitation (LOQs) for most of target analytes compared to previous method employing conventional high-performance liquid chromatography (HPLC) separation.
