High Sensitivity Immunopeptidomics Using Mass Spectrometry
Immunopeptidomics can reveal the diversity in major histocompatibility complex (MHC) bound proteins. However, sample diversity, low abundance and protein sequence variations, and complex data present challenges which require sophisticated mass spectrometry (MS) techniques.
Trapped ion mobility spectrometry (TIMS) coupled with time of flight (TOF) methods can distinguish multiply charged ion signals with superior accuracy compared to conventional methods. Similar to the analysis of single-cell approaches, the timsTOF is an excellent tool for detecting low-concentration, diverse analytes in immunopeptidomics research.
This application note demonstrates how timsTOF and single-cell proteomics (SCP) approaches can be combined to create a robust and sensitive immunopeptidomics workflow.
