The characterization of some of the antigens and allergens in ragweed pollen.
Ragweed extract (RW) and antigens E, K, BPA-R and Ra3 were characterized by  electrophoresis on starch and polyacrylamide gels. RW extract and antigen E were also subjected to crossed immunoelectrophoresis. All the antigens contained isomers and contaminating proteins. RW separated by starch gel electrophoresis was skin tested and allergens unrelated to antigens E, BPA-R, Ra3 and K were found.
