Balancing the use of mass spectrometers in proteomics and in medicine is the use of protein micro arrays. The aim behind protein micro arrays is to print thousands of protein detecting features for the interrogation of biological samples.
Proteome analysis is the investigation of all the proteins present in a cell, tissue or organism at any one time. Since cells are constantly responding to their environment, and the proteins are the workhorses of the cell, the proteome is also changing-reflecting the life of the cell.owever, the genome is only a source of information.

The proteome is the complete set of proteins produced by the genome at any one time.
