Abstract
Human MAF-C (macrophage-activation factor for cytotoxicity)-producing hybridoma H2-E3-5 was prepared by somatic cell fusion of PHA-activated peripheral blood lymphocytes with emetine/actinomycin D-treated cloned human acute lymphatic leukemia cells (CEM). The following activities were assayed: (1) macrophage-migration-inhibitory factor (MIF), (2) macrophageactivation factor for glucose consumption (MAF-G), (3) macrophage-activation factor for O − 2 formation (MAF-O), and (4) macrophage-activation factor for cytotoxicity (MAF-C). After anionexchange chromatography, MAF-C activity could be distinguished from MIF and MAF-O activities. It is shown that MAF-C is not the same as MAF-G from the culture supernatants of CEM 11, a parent cell line of H2-E3-5. Furthermore, MAF-C from H2-E3-5 culture supernatants activated differentiated macrophages but not monocytes.
