Transitioning from nanoflow to standard flow LC/MS: High throughput protein biomarker quantification for clinical research

Liquid chromatography-mass spectrometry-based proteomics has been widely used for protein biomarker discovery and validation. When transitioning from discovery proteomics to targeted protein biomarker quantification, the MRM-based LC/MS method plays an important role in clinical research. To ensure analytical reproducibility and robustness, implementing a standard flow-based triple quadrupole LC/MS system has a tremendous benefit when involving a large cohort.
Learning Objectives:
- Quantitative sensitivity, precision, and accuracy of standard flow-based dynamic MRM method for targeted protein biomarker analysis using the Agilent 6495 LC/TQ
- Successful transfer of PromarkerD method for diabetic kidney disease research from nanoflow to standard flow
- When sample limited, a low flow LC system, Evosep One, coupled to Agilent 6495 LC/TQ could be used for high throughput studies
For Research Use Only. Not for use in diagnostic procedures.
