  • Title: An electrophoretic analysis of Schistosoma mansoni soluble egg antigen preparation.
    Author: Carter CE, Colley DG.
    Journal: J Parasitol; 1978 Jun; 64(3):285-90. PubMed ID: 566313.
    Abstract:
    Schistosoma mansoni soluble egg antigen (SEA) has been examined electrophoretically. Sodium dodecyl sulfate (SDS) electrophoresis of SEA reveals an extremely heterogeneous protein composition. At least 18-20 distinct bands stain with Coomassie blue and at least 6 bands stain with periodic acid Schiff (PAS). Four of the PAS-positive bands stain only faintly with Coomassie blue. The estimated molecular weight range for these proteins is between 16,000 and 200,000 daltons. An acid soluble fraction was isolated from SEA which contained 5 of the 6 glycoproteins. An immunoelectrophoretic analysis of SEA reveals at least 5 distinct precipitin arcs when developed with serum from mice infected with S. mansoni for 16 weeks.
