A murine monoclonal antibody (MAB AF-1) class IgM was raised to a soluble glucomannoprotein extract (GMP) of Candida albicans. Agglutination and indirect immunofluorescence assays with purified MAB showed that AF-1 was directed against a cell-surface epitope shared by C. albicans serotypes A and B, C. tropicalis, C. guilliermondii and C. viswanathii, but not by C. krusei, C. parapsilosis, C. kefyr (pseudotropicalis) and T. glabrata. Treatment with heat, protease or periodate-treated GMP and with other cell-wall extracts of C. albicans provided evidence that the epitope recognised by MAB AF-1 is carried by the polysaccharide moiety of cell-surface glucomannoprotein molecule(s).

Abstract
A murine monoclonal antibody (MAB AF-1) class IgM was raised to a soluble glucomannoprotein extract (GMP) of Candida albicans. Agglutination and indirect immunofluorescence assays with purified MAB showed that AF-1 was directed against a cell-surface epitope shared by C. albicans serotypes A and B, C. tropicalis, C. guilliermondii and C. viswanathii, but not by C. krusei, C. parapsilosis, C. kefyr (pseudotropicalis) and T. glabrata. Treatment with heat, protease or periodate-treated GMP and with other cell-wall extracts of C. albicans provided evidence that the epitope recognised by MAB AF-1 is carried by the polysaccharide moiety of cell-surface glucomannoprotein molecule(s).
