the binding behavior of a competitive inhibitor, n-phenylbenzhydroxamic acid (bha) against horseradish peroxidase (hrp) was studied in order to understand and predict the interaction mechanism of hydrogen donors with the enzyme. the dissociation constants of the complexes of hrp-bha, hrp-donor and hrp-bha-azide were estimated at specified conditions by difference spectroscopy. the binding site ...

background: molecules expressed on the surface of infected erythrocytes (ie) with plasmodium falci-parum play important roles in malaria pathogenesis and immune evasion. some of these molecules are specific adhesive ligands mediating adhesion of ie to the vascular endothelium. in the current study, the antigens exposed on the surface of ie with different isolates and various binding subpopulati...

in this study, we synthesized herceptin conjugated magnetic nanoparticles (hmns) as an alternative probe to discover the levels of her2 (human epidermal growth factor receptor-2) in the surface of cells. these nanoparticles can be used by magnetic resonance imaging (mri) (non-invasive methods) for screening the patients with her2 positive or negative tumors. dextran coated iron oxide nanopartic...
