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...

Antibodies are essential tools of biomedical and biochemical researches. Polyclonal antibodies are produced against different epitopes of antigens. Purified F(ab')2 can be used for animal’s immunization to produce polyclonal antibodies. Human immunoglobulin G (IgG) was purified by ion exchange chromatography method. In all stages verification method of the purified antibodies was sod...

development of a stool antigen immunoassay to detect helicobacter pylori infection requires monoclonal antibody against the specific antigen. alkylhydroperoxide reductase (ahpc) of helicobacter pylori has been described as a specific and unique enzyme for h. pylori and therefore, both h. pylori ahpc and anti-ahpc could be useful in the development of serologic and stool antigen tests, for detec...

Background: The ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. The aim of this study was purification of mouse IgG2a and production of polyclonal antibody against purified mouse IgG2a subclass. Materials and Methods: Mouse IgG2a was purified by ProA affinity. Verification method of the purified antibody was S...

This review focusses on affinity purification of immunoglobulins, a methodology which is a powerful tool to obtain pure and intact antibodies. Affinity techniques allow antibody purification both in a single step chromatographic procedure as well as in complex purification protocols depending on the intention to use the target antibody. The purification strategies for antibodies by interaction ...

a murine igm monoclonal antibody (ma-2c6) with κ-light chains directed against an antigenic determinant of outer surface protein a (ospa) of the lyme disease spirochete, borreliaburgdorferi, is produced. this antibody could bind specifically to ospa antigen of several isolates of b. burgdorferi, but not to the non-lyme disease bacteria such as t. pallidum and b. hermsii. antibody ma-2c6 was pur...

The global antibody market has grown exponentially due to increasing applications in research, diagnostics and therapy. Antibodies are present in complex matrices (e.g. serum, milk, egg yolk, fermentation broth or plant-derived extracts). This has led to the need for development of novel platforms for purification of large quantities of antibody with defined clinical and performance requirement...

In a previous study, we demonstrated a non-chromatographic affinity-based precipitation method, using trivalent haptens, for the purification of mAbs. In this study, we significantly improved this process by using a simplified bivalent peptidic hapten (BPH) design, which enables facile and rapid purification of mAbs while overcoming the limitations of the previous trivalent design. The improved...
