Interaction of murine monoclonal subunit-specific antibodies with phosphofructokinase-1 from Saccharomyces cerevisiae.

چکیده
Murine monoclonal subunit-specific antibodies against heterooctameric phosphofructokinase-1 from Saccharomyces cerevisiae exhibiting no cross-reactivity were purified and characterized regarding complex formation with the native enzyme, immunological reactivity to the SDS-denatured subunits originating from native and proteolytically truncated phosphofructokinase, and protection against proteolytic degradation. Strong complex formation was found with one alpha-specific antibody. Western blotting employing different enzyme forms allowed to localize epitope sites of the alpha-polypeptide chain. Monoclonal antibodies protect phosphofructokinase-1 against chymotryptic degradation.

متن کاملProduction and Characterization of Murine Monoclonal Antibodies Recognizing Conformational and Linear Epitopes Localized on Human IgA2 Molecules
Background: There are two subclasses of human IgA (IgA1 and IgA2) that differ in antigenic properties and in chemical composition. The constant domains of α1 and α2 heavy chains have >95% sequence homology though major structural differences exist in the hinge region. Quantitation of IgA subclass levels depends on the availability of monoclonal antibodies (MAbs) specific for conserved conformat...

The production of murine monoclonal antibody (MAb) has not yet been reported in Iran. The present work describes for the first time the generation of several murine hybridoma clones secreting MAbs directed against human leukocyte surface antigens. The secreted antibodies by hybridoma clones have been screened on different lymphoid and non-lymphoid tissues. Results indicated that of seven h...
