Proteins detected in plasma using proximity extension assay

Proximity extension assays (PEA) based on Olink was performed for 748 proteins based on a longitudinal wellness study covering 86 individuals with four visits during one year at three months intervals. The results are presented as Normalized Protein Expression (NPX) for the individual genes corresponding to these proteins for all females and males respectively.

Below is a summary of the variation between individuals and within individuals for these 748 proteins calculated as the mean standard variation (SD) for each protein within each visit and across all analyzed individuals (n=86), and as the mean SD for each protein within each individual across all visits (n=4), respectively.
