Protein identification services are used to identify single proteins to whole proteomes using LC-MS/MS. They are performed by:

Post-translational modification analysis identifies phosphorylation, acetylation, ubiquitinylation, methylation and many other modifications that control protein function, interactions, signaling and localization :

Quantitative proteomics utilizes metabolic labeling, isotopic tags or label free methods to quantitate proteins and compare different conditions, disease states, and time courses of protein expression changes:

CyTOF is a variant of flow cytometry where antibodies are labeled with heavy metal ion tags and detected by MS allowing for many proteins to be quantitated without interference in the signals: 

Targeted proteomics is used to detect and quantify specific proteins of interest by MS:

Reversed Phase Protein Array provides an antibody based method for quantitating proteins in functional studies of protein expression and modification on multiple states:

Top-down ultraviolet photodissociation fragmentation is a cutting edge technique for obtaining information about the sequence and modification of whole proteins or large protein fragments that preserves combinatorial information about modifications:

Crosslinking, N-terminal labeling, and disulfide bridge analysis give information about protein binding sites and interaction surfaces:

In solution Hydrogen-Deuterium exchange at the peptide or intact protein level:
