Antibodies are a diverse class of glycoproteins that specially bind with antigen and elicit a number of secondary responses in vivo. Most of the applications of antibodies in basic research diagnosis and immunotherapy rely on labeling of the antibody with radiopharmaceuticals. Radiolabeled antibodies are a new class of imaging agents for the detection of sites of disease. True biodistribu...

Antiphospholipid antibodies (APLA) may be detected in normal pregnancies and also may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. In the present study the possible differences in APLA titer between healthy pregnant women and preeclampsia cases without history of thrombosis was examined. The APLA titer in 50 healthy pregnant women with 50 preeclampsia cases wit...

Many different radiolabeled antibodies have been used for radioimmunotherapy and radioimmunoscintigraphy of human diseases in animal experiments. In order to study the in vivo tissue distribution of antibody, we labeled human nonspecific polyclonal IgG with Na125I using chloramine-T method. An animal model was developed by injecting turpentine in the posterior left thigh of Balb/c mice. Tissue ...

Background Beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. Blood transfusion can transmit Cytomegalovirus (CMV) and Toxoplasma gondii. The aim of this study was serological evaluation of these two infectious agents in thalassemia patients. Materials and Methods In a cross-sectional study, the enzymelinked immunosorbent assay (ELISA) testing was pe...

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 sds-...

Background and aims: Toxoplasmosis is a parasitic disease which may cause some laboratory symptoms in infected individuals. One of the main ways of transmition this organism is placenta to fetus pathway. If this transmission occurs in the 3th month of pregnancy, the abortion, central nerve system and ocular disorder will happen. Because of this issue, the precise technique for detection of Toxo...

Objective: The clinical value of IgG anticardiolipin antibody in patients with Behçet's disease with or without vascular thrombosis was evaluated.   Methods: IgG isotype of anticardiolipin (aCL) antibody was assessed in 40 Behçet's disease (BD) patients with venous or arterial thrombosis, 40 BD patients without venous or arterial thrombosis and 80 healthy subjects as controls. The levels of IgG...

OBJECTIVE To examine gluten sensitivity through the measurement of anti-gliadin antibody (IgA and IgG), anti-endomysial antibody (endo-IgA), anti-reticulin antibody (IgG) and anti-transglutamase antibody (IgG) levels in blood samples of autistic in the Riyadh area. METHODS The study took place in the Department of Physiology, Faculty of Medicine, King Saud University, Riyadh between September...
