Reactivity of affinity-purified antibodies with recombinant proteins and synthetic peptides measured by ELISA. (A and C) Anti-R13 and anti-H13 affinity-purified antibodies from cChHD serum 15. (B and D) Anti-R13 and anti-H13 affinity-purified antibodies from SLE serum 5. Purified antibodies were tested at 1:4 dilution. Mean ± SD of OD₄₁₅ values are from three independent measurements. ∗, Significant differences (P < 0.01) were observed between antibody levels against TcP2β and HuP2 and between anti-R13 and -R11 antibody levels when compared with anti-H13 antibody levels.
