Abstract:
Objective To localize Der f 2 in the body of Dermatophagoides farinae.Methods Live mites were embedded.Serial mite paraffin sections were made and checked under light microscope.The sections were incubated with anti-recombinant Der f 2 monoclonal antibody as the first antibody.They were then reacted with the fluorescent isothiocyanate conjugated goat anti-mouse IgG as the secondary antibody.The sections were examined with fluorescent light microscopy.Results Der f 2 reacting with immunofluorescent antibodies was found localized in the tissue and contents of the mid-gut of the mite.Conclusion The major allergen Der f 2 distributes in the gut and fecal pellets of Dermatophagoides farinae.
