    Nanoparticle-enriched mass spectrometry identified over 600 genetic associations with plasma proteins in British South Asian volunteers.

  • 2

    The study detected more than 5,700 protein groups, with mass spectrometry revealing over 3,400 proteins not identified by affinity assays.

  • 3

    Integration with biobank data linked 21 proteins to 44 diseases, highlighting the importance of analytical diversity in genetic studies.
