Response of BLV positive serum with single alanine variants of gp51p16-C. These experiments were performed by a new high-throughput peptide ELISA system. a Sequences of the gp51p16-C peptide and its variants with single alanine mutations are shown in the single-letter amino acid code, and alanine mutation sites are represented in red. b The stimulation index (SI) of four BLV positive serum samples was obtained from cattle experimentally infected with BLV (JBS4, JBS6, JBN1, and JBN2) for individual variants. c Reactions of the serum samples obtained from cattle naturally infected with BLV for individual variants
