Two monoclonal antibodies (MAbs), IC5 and ID5, were produced using spleen cells from BALB/c mice immunized with recombinant estrogen-receptor protein (RER). On immunoblotting, both MAbs reacted with the 67-kDa polypeptide chain obtained by transformation of E. coli and transfection of COS cells with plasmid vectors expressing ER. The epitopes of both MAbs(More)
We report a new and apparently unique human lymphoma cell line termed Deglis. The line was established from a polymorphic centroblastic lymphoma. The cell line and its source carry a dual B-cell and T-cell phenotype and Epstein-Barr virus (EBV) genomes. Simultaneous expression of B-cell (CD19+, CD20+, CD23+, CD37+) and T-cell (CD2+, CD3+/-, CD7+, CD43+)(More)
Based on observations of 66 cases, in which tissues were specially processed to optimize the simultaneous preservation of cell membrane antigens and morphology, we provide evidence in favor of a relationship between follicular dendritic reticulum cells (FDRC) and Reed-Sternberg (RS) cells of Hodgkin's disease (HD) other than the lymphocyte predominance(More)
Using spleen cells from athymic nude mice grafted with Ichikawa tumour, we have generated the monoclonal antibody IND.64, which detects a proliferation-associated nuclear antigen. Immunoblotting analysis with IND.64 showed a double band with apparent molecular weights of 395 and 345 kD. In normal human tissues, the antigen detected by IND.64 was expressed(More)
AIMS--To generate new monoclonal antibodies directed against melanoma associated antigens using a new melanoma cell line, KAL. METHODS--The melanoma cell line was established in culture from a lymph node metastasis of malignant melanoma. Normal Balb/c mice were immunised with KAL cells. Splenocytes were used for fusion experiments using standard techniques.(More)
