Background:

  • Classical proteomics and immunoassays often lose information on protein diversity.
  • Affinity mass spectrometry (AMS) offers a method to overcome these limitations.
  • Understanding protein variants is crucial in biological and medical research.

Purpose of the Study:

  • To describe a high-throughput affinity mass spectrometry (AMS) protocol.
  • To apply AMS for population proteomic screening of human plasma cystatin C.
  • To highlight the capability of AMS in capturing protein signatures.

Main Methods:

  • High-throughput affinity mass spectrometry (AMS) protocol.
  • Selective isolation of target proteins from complex biological fluids.

    • Main Results:

    • AMS successfully isolated target proteins from human plasma.
    • High-content mass spectrometry data revealed diverse forms of cystatin C.
    • The study demonstrated the ability to detect wild-type, post-translationally modified, and genetically modified proteins.

    Conclusions:

    • High-throughput AMS is effective for population-level proteomic screening.
    • AMS provides deeper insights into protein diversity compared to classical methods.
    • This approach is valuable for analyzing complex biological samples like human plasma.
