  1. The percentages of IgE binding of deletion mutants relative to whole rCyn d 1 are shown for individual serum (P1–P4) and pooled patient sera (n = 10) as determined by ELISA. The percentage binding was calculated using the OD readings obtained through direct ELISA. The OD reading with whole purified rCyn d 1 was expressed as 100% and the OD of the deletion mutants were expressed in percentage relative to that of whole rCyn d 1. The mean ± SEM is shown in the bottom line.
