data independent analysis on thermo scientific orbitrap ms systems
DESCRIPTION
Data-independent acquisition (DIA) is becoming increasingly important for quantitative proteomics, especially for large-scale targeted protein quantification. DIA provides better reproducibility, acquires fragment ions of all precursors, and breaks through the limit of quantification throughput. DIA with the Thermo Scientific™ Orbitrap™ LC-MS enables ultimate flexibility. The Thermo Scientific™ Orbitrap™ LC-MS pushes the boundaries of large scale quantitation, with highest mass accuracy, Orbitrap high resolution, short cycle times, and narrow isolation windows.

Main Topics
Introduction: Why Do DIA?
• Advantages of data independent acquisition, where, when, and why its useful
Where does DIA fit in?
• Positioning of DIA methods with other workflows like DDA and PRM
Data Independent Analysis
• Prerequisites, hardware and software
Challenges in DIA
• The three characteristics of the ideal DIA experiment and the compromises among them
Flexibility in DIA Methods
• Multiple varieties of MS2 and MS1+MS2 methods to suit experimental needs
Conclusion: If you Are Going to Make an Archive…
• The new Thermo ScientificTM Q ExactiveTM HF MS as a DIA workhorse
