As expected, about 30 of the IgG autoAbs that were identified to be elevated in SLE using ProtoArray were well-known SLE-specific autoAbs, e.g., anti-DNA, anti-Sjögren’s-syndrome-related antigen A (anti-Ro/SSA), anti-Sjögren syndrome type B antigen (anti-La/SSB), anti-small nuclear ribonucleoproteins (anti-snRNP), anti-histone, and anti-ribosome proteins [6], thus validating the authenticity of the ProtoArray platform for identifying disease-associated autoAbs. Here, SSB is linked to systemic lupus erythematosus.
