-Single-cell proteomics: Used to study the protein composition and changes within single cells, revealing cellular heterogeneity.
-Immunopeptidomics: Studies peptide molecules in the immune system, aiding in the understanding of immune response mechanisms.
-Epiproteomics: Investigates post-translational modifications of proteins, such as phosphorylation and acetylation, to uncover regulatory mechanisms of protein functions.
-Post-translational modification proteomics: Focuses on protein post-translational modifications and their impact on protein function.
