Correlation diagrams of PM1-α, PM/Scl-75a, PM/Scl-75c and PM/Scl-100. A panel of sera tested previously for reactivity to recombinant polymyositis/scleroderma (PM/Scl) components (PM/Scl-75a, PM/Scl-75c and PM/Scl-100) was assayed for anti-PM1-α peptide reactivity in an ELISA [18]. Correlation diagrams are shown comparing the peptide ELISA with the recombinant proteins (a)–(c) for all sera (n = 81) and (b)–(f) for only the sera of PM/Scl patients (n = 36).
