Sensitivity of sandwich enzyme-linked immunosorbent assay for Cryptococcus neoformans polysaccharide antigen is dependent on the isotypes of the capture and detection antibodies

J Clin Microbiol. 1995 Mar;33(3):765-8. doi: 10.1128/jcm.33.3.765-768.1995.

Abstract

Immunoglobulin M (IgM) and IgG1 monoclonal antibody isotype switch variants to Cryptococcus neoformans capsular polysaccharide were used to study the sensitivity of a double sandwich enzyme-linked immunosorbent assay (ELISA). The most sensitive ELISA configurations used IgG1 monoclonal antibody absorbed on polystyrene plates or IgM immobilized with goat antisera for antigen capture.
