Higher levels of IgE-containing immune complexes (IC) have been reported in sera from patients with allergic diseases than in sera from controls. To evaluate the possibility of an IC-mediated mechanism in the pathogenesis of bronchial asthma, we measured circulating C3-containing IgE IC (C3-IgE IC) using anti-C3 ELISA from 20 house dust mite (HDM)-sensitive asthmatics, 20 non-atopic asthmatics,...

African patients with Leishmania donovani infections have signs of strong systemic inflammation and high levels of circulating immune complexes (IC) and rheumatoid factor (RF), all serologic markers of rheumatic disease. As inflammation in general is associated with citrullination, we sought to investigate ACPA responses in Sudanese Leishmania patients. Serum samples were collected from Sudanes...

Purpose: Immunocytokine (IC) hu14.18-IL2 is a fusion protein of humanized antidisialoganglioside (GD2) antibody (hu14.18) and interleukin (IL)-2. Sixty-one melanoma and neuroblastoma patients received IC in phase I/Ib studies. Patient sera were examined in ELISA to determine if an anti-IC antibody response occurred during treatment. Experimental Design: Serum was assayed for anti-idiotypic anti...

OBJECTIVE Organophosphorus (OP) pesticides are considered hazardous substances because of their high toxicity to nontarget species and their persistence in the environment and agricultural products. Therefore, it is important to develop a rapid, sensitive, and economical method for detecting OP pesticides and their residues in food and the environment. METHODS A broad, selective monoclonal an...

AIM To detect and identify the causative agent or agents of the following clinical symptoms which were fever, lack of appetite, salivation, vesiculation, erosions of the buccal mucosa, nose, and feet. The signs vary from mild to severe. The mortality rate of the disease is high. The morbidity rate reaches up to 100%. Sheep also show bloody diarrhea and rapid respiration. Sheep flock resident in...

A new method for specific antibody production was developed using antibody (Ab)-pesticide complex as a unique immunogen. Parathion (PA) was the targeted pesticide, and rabbit polyclonal antibody (Pab) and mouse monoclonal antibody (Mab) were used as carrier proteins. The Ab-PA complexes were generated by conjugating the two antibodies with an excessive dosage of PA. It was shown that the sensit...

soybean mosaic virus (smv) which belongs to the virus family potyviridae, causes a disease in soybean that is present in soybean-growing areas of the world, and is widely distributed in northern iran. detection of smv is very important for disease management. in the present study several serological and molecular (nucleic acid- based) methods of rapid virus detection were compared. serological ...
