title: Comparison of antigenic and allergenic components of Holoptelea integrifolia pollen collected from different source materials.
abstract: Antigenic extracts prepared from pollen samples collected at weekly intervals during the same season did not exhibit significant variation in protein concentration. Stored pollen samples from different years, however, showed highly significant variations in protein concentration. The protein content of samples from different ecozones of India also varied (CV = +/- 32%). The IEF and SDS-PAGE patterns were almost identical in samples from the same season, but were variable in the samples stored from different years and different parts of India. IgE binding proteins from different samples also varied depending on the overall protein profiles. Almost all the patients, however, showed IgE binding to four proteins at 50, 60, 66 and 70 kD, indicating the important allergenic components of Holoptelea integrifolia.
