There are a virtually unlimited number of combinations of modern proteomic and mass spectrometry approaches that can be implemented to identify and characterize proteins. These applications can be applied in "discovery mode", where the protein of interest is not necessarily known a priori, or in "targeted mode", where the sequence and modifications of a particular protein of interest are interrogated.

While not an all-inclusive list, several of the most common study types are listed below. 

Protein Identification

Gel Bands
Protein in solution or lyophilized

Investigator provides Coomassie or Silver stained gel band or complete gel, in a solution of known composition, or in lyophilized form. 


Peptide Analysis

Protein in solution or lyophilized

Investigator provides peptide sample in a solution of known composition or in lyophilized form.
