Figure 2: Comparison of levels of s-CCNL2-Abs. a, Shown are the positive rates of s-CCNL2-Abs in the patients with esophageal SCC, healthy donors, and patients with colon carcinoma or mammary carcinoma examined by ELISA. b, The levels of s-CCNL2-Abs in healthy donors (HD), gastric cancer (GC), colon carcinoma (CC) and esophageal SCC (EC) examined by AlphaLISA are shown. P values were calculated by Mann-Whitney U test. c, As a validation test, the s-CCNL2-Abs levels were analyzed by AlphaLISA using another set of sera.
