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 SP2/0-Ag 14 myeloma cells. Monoclonal and monospecific, polyclonal antibodies to these cytoplasmic antigens find application in the im- munodiagnosis of Candida infections.
A procedure is provided for preparing partially purified cytoplasmic antigen of pathogenic Candida species for administration to splenocyte-donating mice. Also provided is a method for the biochemical purfication of cytoplasmic antigen of a pathogenic Candida species used for the preparation of monoclonal and monospecific, polyclonal antisera thereto.
ATCC #HB-8397 和 ATCC #HB-8398 这两个新型杂交瘤细胞系能产生单克隆抗体,该抗体对白色念珠菌三种密切相关的细胞质抗原所共有的单一决定簇具有单特异性。这些抗原的分子量分别为 120-135Kd、48-52 Kd 和 35-38Kd。杂交瘤是由免疫 BALB/c 小鼠的脾细胞与 SP2/0-Ag 14 骨髓瘤细胞融合而成。这些细胞质抗原的单克隆和单特异性多克隆抗体可用于念珠菌感染的诊断。
本研究提供了一种制备部分纯化的致病性念珠菌细胞质抗原的方法,用于给捐献脾细胞的小鼠注射。还提供了一种用于制备单克隆和单特异性多克隆抗血清的致病性念珠菌细胞质抗原的生化纯化方法。
