Vinculin specific cDNA clones were isolated from chicken embryo fibroblast (CEF) cDNA library in lambda gt11. The clones, ranging in size from 2.8 to 5.0 kb, were initially selected by rabbit antibodies to vinculin. Their identity was further confirmed by their specific reactivities with a battery of different vinculin-specific monoclonal antibodies. Southern blot analysis of restriction enzyme...

Background and Aim: IPB-D2 chickens are selected from IPB-D1 due to their disease-resistance characteristics. One-way evaluate the strength of a chicken’s immune system is by examining number circulating T lymphocytes. This assessment can be conducted using modern analytic method called flow cytometry which relies on monoclonal antibodies detect relative proportions each cell measure quality qu...

background: antiphospholipid antibodies (apl) are a heterogeneous family of anti-bodies associated with thrombosis and other complications. objective: to study the prevalence of apl in patients with thrombosis at aleppo university hospitals, syria. methods: one hundred and fifty-seven patients with venous and arterial thrombosis and 63 healthy controls were studied. anticardiolipin antibodies (...

Toxoplasma gondii is an intracellular apicomplexan parasite infecting warm-blooded vertebrate hosts, with only early infection stage being contained with drugs. But diagnosis differencing early and late infection was not available. In the present investigation, 2-dimensional immunobloting was used to explore early and late infections in chickens. The protein expression of T. gondii was determin...

In a previous study, we have developed several chicken monoclonal antibodies (mAbs) against Eimeria acervulina (EA) in order to identify potential ligand molecules of Eimeria. One of these mAbs, 6D-12-G10, was found to recognize a conoid antigen of EA sporozoites and significantly inhibited the sporozoite invasions of host T lymphocytes in vitro. Furthermore, some of these chicken mAbs showed c...

In chicken, three structurally distinct nuclear lamin proteins have been described. According to their migration on two-dimensional gels, these proteins have been designated as lamins A, B1, and B2. To investigate the functional relationship between chicken lamins and their mammalian counterparts, we have examined here the state of individual chicken lamin proteins during mitosis. Current model...

PURPOSE To define the nature and estimate the molecular weight range of soluble endogenous retinal trophic activities on cone photoreceptor survival in two models of cone degeneration. METHODS Diffusible factors from dissociated retinal cell cultures of 8-day normal-sighted (C57BL/6J) mice were tested for cone-survival-promoting activity by two approaches and by using two independent photorec...

Materials and Methods Infectious bursal disease (IBD) is a highly contagious disease of young chicken caused by infectious bursal disease virus (IBDV), characterized by immunosuppression and mortality generally at 3 to 6 weeks of age [1]. It is economically important to the poultry industry worldwide, due to increased susceptibility to other diseases and negative interference with effective vac...
