However, we also demonstrate that although the complex is internalized and presented, there is no improvement in antigen presentation when compared to soluble antigen
and thus it does not enhance indirect allopresentation.
In a previous publication (24) we have demonstrated that the proliferative response of mononuclear cells from patients with Chagas' disease to bands of soluble, epimastigotes and trypomastigotes, antigens was poor with an important down regulation (DR) that was more frequent and intense with soluble antigens
Binax NOW Legionella Urine Antigen Test is a rapid immunochromatographic assay used for the early diagnosis of Legionnella pneumophila serogroup 1 infection through detection of a specific soluble antigen
present in the urine of Legionnaires Disease patients.
have found that T4 cells from AIDS victims "have an intrinsic defect in their ability to recognize and respond to soluble antigen
," says a report by H.
Intravenous administration of soluble antigen
in the absence of adjuvants is another well documented procedure to induce tolerance [21, 22].
Two different applications were used for detection and quantification of a soluble antigen
and in a serological assay, respectively.
Using a competitive-binding or displacement-type assay, we can detect extremely small quantities of a soluble antigen
added to the system.
