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...

the witches’ broom disease of lime trees is a destructing disease caused by the bacterium candidatus phytoplasma aurantofolia (1). the disease is prevalent in oman,united arab emirates and iran. to restrict the spread ofthe infected trees, detection of the causative bacteriumis crucial. besides pcr-based methods, antibodies can beapplied for detection of pathogen-infected cells.recently shahrya...

conclusions the r-b-flagellin carried antigenic epitopes just like the native flagellin, while the polyclonal antibody raised against it exhibited functional activity. results the polyclonal antibodies raised against this r-b-flagellin inhibited the motility of the homologous pao1 strain of p. aeruginosa, which significantly decreased the invasion of the pao1 strain into the a549 cells and also...

the rotavirus nonstructural protein 4 (nsp4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. however, the complete biological effect of nsp4 remains to be clarified. since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein...

introduction: polyclonal antibodies are required to be affinity purified. improved purification methods of polyclonal antibody provide an opportunity to pick the most purified immunoglobulins as a primary or secondary antibody in immunoassays that are included in many vaccine studies. two common techniques for purifying proteins is salt precipitation and chromatography purification. our work fo...
