cystic echinococcosis (ce) is an infection caused by the larval stage of echinococcus granulosus. this is widely distributed through iran, where a variety of animals act as intermediate host. the immunogenic antigens (ag) of different compartments of the hydatid cyst have been already determined. one of these compartments is the laminated layer (ll). we have extracted a protein with the mw of 2...

serology and dna techniques are employed for human leukocyte antigen (hla) typing in different transplant centers. results may not always correlate well and may need retyping with different technique. all the patients (with aplastic anemia, thalassemia, and immunodeficiency) and their donors, requiring hla typing for bone marrow transplant were enrolled in the study. serological hla typing was ...

The virus-like particle (VLP) capture assay is an immunoprecipitation method, commonly known as a 'pull-down assay' used to purify and isolate antigen-displaying VLPs. Surface antigen-specific antibodies are coupled to, thus immobilized on solid insoluble matrix such beads. Due their high affinity the target antigen, these can VLPs decorated with cognate antigen anchored in membrane envelope of...

Background: Hydatidosis is one of the cosmopolitan parasitic zoonoses caused by the larval stage of Echinococcus granulosus. Diagnosis of hydatidosis is still an unresolved problem. Serological tests using crude antigens for diagnosis of E. granulosus are sensi-tive, however their specificity are not satisfactory. Therefore, WHO recommended spe-cific serological methods using specific antigens,...
