Hypothesis
This study aimed to develop a rapid HILIC-MS/MS method for analyzing approximately 50 amino acids and related compounds in human plasma.
Conclusion
The developed method can accurately and efficiently detect 48 endogenous amino acids in human plasma without complex derivatization.
Supporting Evidence
- The method was validated for 48 target analytes with high linearity and precision.
- Isotope-labeled internal standards were used to enhance accuracy.
- The method demonstrated broad application prospects in clinical diagnosis and metabolic research.
Takeaway
Researchers created a new way to measure amino acids in blood quickly and easily, which can help doctors understand health better.
Methodology
The study used hydrophilic interaction liquid chromatography coupled with tandem mass spectrometry to analyze plasma samples.
Limitations
The method may still be affected by matrix effects from the plasma samples.
Participant Demographics
Plasma samples were collected from 20 control individuals.
