Human Plasma Proteome

By William Aird

The plasma proteome is characterized by an extremely high abundance of a small set of plasma proteins (20 proteins account for 99% of the protein by weight), most of them familiar to the clinician.

It is humbling to learn that plasma contains over 4,000 additional proteins, whose signature, yet to be mined, holds important clues about the health of tissues and organs and the potential for new diagnostics and tailored treatment.
