It has been discovered that the E or Amb a I antigen of ambrosia pollen constitutes a family or families of proteins. CDNAs coding for Amb a I, the major human allergen of ambrosia, and for Amb a II, peptides derived from Amb a I or Amb a II, antibodies acting against these peptides, as well as therapeutic methods for treating susceptibility to ambrosia in humans are described. |
