Circadian variation of secretory IgA in nasal secretions from normal subjects.
In normal subjects the concentration ratio of secretory IgA (sIgA) to total IgA in nasal secretion was measured by means of enzyme-linked immunosorbent assays (ELISA). No marked circadian variation was disclosed in the sIgA/IgA ratio in nasal secretion.
