ELISA titers of rabbit antisera to synthetic peptides. Rabbit antipeptide antisera were serially diluted fourfold and reacted with the corresponding peptide bound to an ELISA plate, following the procedure described in the text. Titer was defined as the highest serum dilution at which the ELISA OD was larger than the mean OD value of the preimmune sera of all of the rabbits plus 3 standard deviations.
