Immunoblotting (western blotting) is a rapid and sensitive assay for the detection and characterization of proteins that works by exploiting the specificity inherent in antigen-antibody recognition. It involves the solubilization and electrophoretic separation of proteins, glycoproteins, or lipopolysaccharides by gel electrophoresis, followed by quantitative transfer and irreversible binding to...

toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. the life cycle of the parasite includes an asexual reproduction in intermediate hosts (mammals and birds) and a sexual reproduction in definitive hosts (felidae). cats are both the intermediate and the definitive host for t. gondii. the aim of this study was to investigate anti-t. gondii antibo...

helicobacter pylori (h.pylori) is an etiologic factor for chronic gastritis and peptic ulcers. serological testing of h.pylori infection is common in iran, as other parts of the world. there are geographical variations in the humoral immune response to various h. pylori strains in different parts of the worl. we studied the immunogenic proteins of h.pylori by means of an immunoblot assay with a...

conclusion the identification of immunodominant proteins adapted to the physiological and genetic conditions of the host is an appropriate diagnostic approach, which could be associated with improved sensitivity and specificity of serologic tests. results four immunodominant proteins (23, 28, 30, 41 kda) were recognized with strongyloidiasis sera in 0.1 diluted serum. none of the proteins react...
