  • Title: Seasonal variation of IgE and IgG antibody of some atopic patients against the pollen grains of selected plant species.
    Author: Ruffin J, Shaw S, Banerjee S.
    Journal: Cytobios; 1990; 63(254-255):167-75. PubMed ID: 2292188.
    Abstract:
    Several steps were taken to determine the seasonal variation of IgE and IgG antibody against Short Ragweed, Timothy Grass, Tag Alder and White Ash. Extracts of the above pollen grains were separated into their allergen components using SDS-gel electrophoresis and transblotted to nitrocellulose membrane (Western blotting) and probed with sera from atopic patients in every month (August 1987-July 1988). The IgE and IgG antibody against the specific-allergens were detected by double antibody immunoenzyme assay. The percentage of binding was determined by using a 620 video-densitometer. Results indicate that there was no reasonable IgE antibody before the pollination season, but IgEAb appeared after the season and was detectable for several months. Negligible amounts of IgGAb were observed.
