Serum antibody levels of glioma SEREX antigens. cDNA inserts of identified clones were recombined in-frame into pGEX vectors that express recombinant GST fusion proteins. Using the fusion proteins as antigens, the levels of antibodies were examined by the ELISA and shown by the ordinate, as (A) CENPF, (B) MIF, (C) M-RIP, (D) RBBP8, (E) RPLP0, (F) TAF7, (G) TLN1, (H) TGFBI, (I) UNC45A. The significance of differences among healthy donors, patients with low-grade glioma and with high-grade glioma was calculated using Kruskal Wallis H-test and Mann–Whitney U-test with Bonferroni correction. The box-and-whisker plots display the 10th, 25th, 50th, 75th and 90th percentiles.
