Polyvinyl alcohol-glutaraldehyde as solid-phase in Elisa for Schistosomiasis
Soluble adult Schistosoma mansoni antigen preparation (SWAP) was covalently fixed onto polyvinyl alcohol-glutaraldehyde discs and an enzyme linked-immunosorbent assay (ELISA) was set up.

| Summary: | Soluble adult Schistosoma mansoni antigen preparation (SWAP) was covalently fixed onto polyvinyl alcohol-glutaraldehyde discs and an enzyme linked-immunosorbent assay (ELISA) was set up. The best conditions for the assay were established and it was found that small amount of antigen such as 1.5 µg was required. A comparison between this procedure and the conventional ELISA was proceeded. A reliable method of antigen immobilization was achieved and the low prices of the employed reagents are economically attractive Polivinil álcool-glutaraldeido como fase sólida em ELISA para esquistossomose Preparações antigênicas solúveis de Schistosoma mansoni adulto (SWAP) fixadas covalentemente em discos de polivinil álcool-glutaraldeido foram usadas em teste de ELISA. As melhores condições para o ensaio foram estabelecidas e foi encontrado que uma quantidade mínima de antígeno, em torno de 1,5 m g é necessária. Comparação entre este procedimento e o de ELISA convencional foi estabelecida. Um método seguro de imobilização do antígeno foi alcançado e os baixos preços dos reagentes empregados são economicamente atraentes |
