[Detection of secretory immunoglobulin A in vaginal fluid of hysterectomised women].

Secretory immunoglobulin A (S-IgA) or the secretory component (SC) in vaginal fluid of hysterectomised patients were established by means of simple and double immunodiffusion, according to Mancini or Ouchterlony, using an S-IgA standard. Since S-IgA was recorded from vaginal fluid, general questions were raised for origin and transport mechanisms of this localised immunoglobulin.
