Abstract From the Canadian patent

Abstract Two novel hybridoma cell lines, ATCC #HB-8397 and ATCC #HB-8398 produce monoclonal antibody monospecific to a single determinant shared by a set of three closely related cytoplasmic antigens of Candida albicans. The antigens have molecular weights of 120-135 Kd, 48-52 Kd and 35-38, Kd. The hybridomas are formed by fusing splenocytes from immunized BALB/c mice with SP2/O-Ag 14 myeloma cells. Monoclonal and monospecific polyclonal antibodies to these, cytoplasmic antigens find application in the immunodiagnosis of Candida infections. A procedure is provided for preparing partially purified cytoplasmic antigen of pathoganic Candida species for administration to splenocyte-donating …
