Abstract
|
|
|
|
Seven monoclonal antibodies were produced by fusing splenocytes from Balb/C mouse immunized with partially purified human interferon-a (HUIFN-a) with NSO plasmacytoma cells. aery were identified as five IgG class (432.22: IgG2b/n, 460.52: IgG2b/a , 548.46: IgG2a/n , 573.10: IgG2b/h , 625.12: IgG2b/n ), one IgA class (460.50: IgA/n ) and one IsM class (465.27: IgA/n ), and all of them revealed highly sensitive to HUIFN- a IgG class monoclonal antibodies have pts ranged from 8.2 to 8.6. Ascites fluids produced from primed Balb/c mice and were purified through column chromatography. The cytopathic effect (CPE) inhibition assay to examine neutralization of HuIFU-a by IgG class monoclonal antibodies, gave that MAbs 460.52, 548.46, 573.10 can neutralize HUIFU- a arith varying degrees except 432.22. Therefore, it is deduced that these various monoclonal antibodies may recognize the distinct epitopes on HUIFN-a.
