Monoclonal antibodies to murine interferon-gamma: affinity purification and molecular characterization of murine interferon-gamma. 1985

G Gribaudo, and F Cofano, and M Prat, and S Landolfo

Monoclonal antibodies (MAb), AN-18.17.24, obtained by fusing the murine myeloma cell line Ag8.653 with spleen cells from rats immunized with murine interferon gamma (IFN-gamma) produced by the phorbol myristic acetate(PMA)-stimulated T-cell lymphoma L12-R4, were shown to be specific for MuIFN-gamma. An immunoadsorbent column was prepared and used for large-scale purification of MuIFN-gamma produced either by PMA-stimulated L12-R4 cells or by normal T-lymphocytes stimulated with Con A and interleukin 2. The purified product from L12-R4 cells, which retained biologic activity, was made up of two proteins (Mr = 16,500 and 17,500) as determined by sodium dodecyl sulfate gel electrophoresis. By contrast MuIFN-gamma produced by normal T-lymphocytes resulted in two proteins with Mr of 20,600 and 21,800 as determined by sodium dodecyl sulfate gel electrophoresis. These results indicate that MuIFN-gamma produced by L12-R4 tumor cells or by normal T-lymphocytes differ in their molecular weight, probably because of different degrees of glycosylation of the same molecule.

UI	MeSH Term	Description	Entries
D007371	Interferon-gamma	The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.
