Method Description

The qualitative immunoenzymatic determination of IgG-class antibodies against Schistosoma mansoni is based on the enzyme-linked immunosorbent assay (ELISA) technique.

 

Microtiter strip wells are precoated with Schistosoma mansoni antigens to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material, horseradish peroxidase-labelled protein A conjugate is added. This conjugate binds to antigen-antibody complexes. The immune complex formed by the bound conjugate is visualized by adding tetramethylbenzidine substrate, which gives a blue reaction product.

 

The intensity of this product is proportional to the amount of Schistosoma-specific IgG antibodies in the specimen. Sulfuric acid is added to stop the reaction. This produces a yellow endpoint color. Absorbance at 450 nm is read using an ELISA microwell plate reader.(Package insert: NovaLisa Schistosoma mansoni, Gold Standard Diagnostics; V SCHG0410engl,dt,fr,it,es18082009-JH Rev 01)
