Figure 1From: Identification of a novel SEREX antigen family, ECSA, in esophageal squamous cell carcinoma Amino acid sequence homology among ECSA-1, -2 and -3 and HCA25a. Identical amino acids and homologous amino acids are indicated by asterisks and dots, respectively. The position numbers of each first amino acid are indicated. The positions of the synthetic peptides, HCA-57/71, HCA-81/97 and HCA-26/41, are also shown.Back to article page
