TLDR The technology can help diagnose and subtype autoimmune diseases by identifying specific autoantibodies.

The study developed a high-density protein microarray with 2,413 nonredundant purified human proteins for antibody screening and serum profiling. It demonstrated applications in characterizing antibody binding and profiling the antibody repertoire in sera from patients with autoimmune diseases, including alopecia and arthritis. The protein chips showed high sensitivity and specificity, identifying specific autoantigens like p69 and tumor suppressor p33 ING in alopecia patients' sera. This technology offered advantages such as reduced time, small sample volumes, and suitability for automation, suggesting potential diagnostic applications for autoimmune diseases and hair loss conditions.
