Protein detected in human plasma by mass spectrometry

In this chapter the estimated concentrations of proteins detected in human plasma based on mass spectrometry-based proteomics is presented. Protein concentrations were quantified by mass spectrometry-based plasma proteomics and estimated from spectral counts in the publicly available Peptide Atlas build (Human Plasma 2021-07). This data set contains estimated concentrations for 4066 proteins, including both proteins that are actively secreted to plasma, but also locally secreted proteins and intracellular proteins that leak into the blood stream.
