Rat monoclonal antibody 6.10 recognizes a 175-kDa protein expressed in all BALB/c mouse transitional cell bladder carcinomas tested, in epithelial cells of the mouse embryo, and in a few epithelial cells of adult mice. The antibody was used as an immunogen to generate two mouse monoclonal antibodies, 21D9 and 43A10, which bind to idiotopes on antibody 6.10 associated with the binding site for t...

The purpose of this study was to determine whether the abnormal serum factors of acquired hemolytic anemia in patients with leukemia and lymphoma could be characterized as antibody by the immune adherence technique. The pathogenesis of this disorder has not been completely explained and it was felt that the study of specific immunologic reactions might help to determine whether these serum fact...

Recent progress in the study of antigen-antibody reactions of biologicals in agar gel demands improvement of existing gel-cutting devices. For an ideal comparison of two or more antigenic preparations against an antiserum, it is necessary to obtain a critical distance between the ( antigen and antibody cups and to obtain a partial or complete identity of precipitinogen in adjacent cups. However...

objectives: ctxb (cholera toxin b subunit) contributes to a vaccine's efficacy by stimulating production of the anti-ctxb antibody. various attempts have been made to increase production of this antibody. chitosan is a mucoadhesive polysaccharide that has tremendous potential for oral vaccine delivery in terms of its exclusive features that include biocompatibility, biodegradability, high charg...

the measurement of antibody responses of animals exposed to bvdv either through a natural exposure or an immunization protocol is still a standard procedure. for bvdv, the test formats have been largely limited to elisa which is a valuable diagnostic test to measure the level of bvdv specific antibodies as well as antigen in blood samples. in the present study, 120 blood samples were collected ...

This work was designed to provide high protective, long-lasting immunity against FMD by enhancing the immunogenicity of trivalent vaccine using carbomer as adjuvant G. pigs an alternative cheapest animal model for quality control testing prepared vaccines formulae. Guinea were chosen experimental models develop concepts and techniques study PD50 because similarities clinical symptoms in these a...

Background and Aims: Influenza is an acute respiratory illness that is caused by a virus belonging to Orthomyxoviridae family. This virus spreads rapidly every year in cold season and leads to morbidities and mortalities especially in adults and children, which causes billions of dollars of economic losses. Accordingly, development of a rapid, sensitive and inexpensive laboratory diagnosis base...

Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
