The major serological antigen (MSA1) from Schistosoma mansoni eggs is a "circumoval" precipitinogen.
A monoclonal hybridoma antibody to the major serological egg antigen of Schistosoma mansoni (anti-MSA1) reacted with schistosome eggs, forming a circumoval precipitate. This precipitate was seen when anti-MSA1 was incubated with S. mansoni, S. haematobium, and S. japonicum eggs.
