Abstract
Spleen cells from BALB/c mice immunized with human leukocyte interferon gamma (HuIFN-gamma) were fused with mouse NSO myeloma cells. Nine hybridoma lines were found secreting monoclonal antibodies (MoAb) which were able to neutralize the antiviral activity of HuIFN-gamma. All nine MoAb inhibited also the antiproliferative activity of HuIFN-gamma. The ability of tested MoAb to inhibit both the antiviral and antiproliferative activities of HuIFN-gamma supports the suggestion that a common domain on HuIFN-gamma molecule might be responsible for both biological activities. However, ELISA and/or RIA proved unsuitable for detection of these specific MoAb.
