Proteomics is the analysis and study of proteins. The proteome is set of proteins that is produced or modified by an organism or any system that enables the identification of every increase in numbers of protein. It is highly benefitted for genetic information of various genome projects that includes the human Genome. The exploring of proteomes from all level of composition, structure and activity. It is an important component of functional genomics but often used specifically to protein purification and mass spectrometry.

Applications of proteomics

The major application is to study of human genes and proteins for the identification of potential new drugs for the treatment of diseases. Genome and Proteome information is to detect the proteins associated with a disease. Proteomics is also used in plant and insect interactions which helps to identify the genes involved in the defensive response of plants to herbivory. The human plasma proteome has become a major goal in the proteomics arena. proteome to generate a diagnostic tool since cancer is associated with glycosylation of proteins and the technological advancements and continuous developments seem to result in effect of such a common life style on the plasma proteome. These cell types, tissue types and species are particularly using deep mass spectrometry which is a resource for research in fields like cancer biology, developmental and stem cell biology, medicine and evolutionary biology.
