| Figure 3: Biosensor binding assay. Overlay of association kinetics upon addition of IgG purified from serum of 8 SSc patients (SSc IgG) to surface-bound PDGFRα. Responses of additions of IgG purified from serum of 8 healthy controls (HC IgG) are included. The red line with asterisk indicates the signal of the unique HC IgG sample characterized by a response similar to SSc IgG. |
