In order to improve the sensitivity of proteomic analysis, our group has developed a chicken antibody based column that has successfully depleted high abundance proteins (HAPs) from human plasma prior to mass spectrometry analysis. The use of chicken as a host for polyclonal antibodies production conveys many advantages, including but not limited to, the capabilities of producing large quantiti...
هلیکوباکتر پیلوری یک باکتری گرم منفی اسپیرال و میکروآئروفیل است که در لایه مخاطی معده انسان تکثیر یافته و ایجاد عفونت می نماید. عفونت ایجاد شده توسط این باکتری که با تخریب بافت پوششی معده همراه است، منجر به التهاب مزمن معده می گردد که می تواند سبب ایجاد زخم های معده و دوازدهه گردد. مشکلات ناشی از درمان با آنتی بیوتیک ها باعث شده است که محققین رویکردهای جدیدی برای درمان عفونت های ناشی از h.pylor...
Alternatives to antibiotics for the treatment and prevention of infections are badly needed. Passive immune therapy with avian antibodies (immune globulin, IgY) from eggs of hens, that have been vaccinated with a specific microbe, is a real alternative.
The stabilization of antibody-latex complexes at high salt concentration is an event that cannot be explained by the widespread DLVO theory. Adsorption of antibodies on polystyrene latex usually leads to a loss in colloidal stability. However, after the expected particle aggregation induced by an increase in ionic strength, an 'anomalous' restabilization occurs when the electrolyte concentratio...
Lumazine synthase from Brucella spp. (BLS) is a highly immunogenic decameric protein. It has been previously described as a carrier of peptides or proteins to increase their immunogenicity in different animal species, but its activity has never been evaluated in chickens. In this work, the use of BLS to improve the antibody response against bovine rotavirus (BRV) VP8d protein in laying hens was...
The production of anti-snake venom from large mammal's blood has been found to be low-yielding and arduous, consequently, antivenom immunoglobulins for treatment are achieved regularly as polyvalent serum. We have standardized an undemanding technique for making purified immunoglobulin IgY antivenom consisting of polyclonal antibodies against coral snake venom in the egg yolk of immunized hens....
Enterohemorrhagic Escherichia coli (EHEC), a subset of Shiga toxin producing E. coli (STEC) is associated with a spectrum of diseases that includes diarrhea, hemorrhagic colitis and a life-threatening hemolytic-uremic syndrome (HUS). Regardless of serotype, Shiga toxins (Stx1 and/or Stx2) are uniformly expressed by all EHEC, and so exploitable targets for laboratory diagnosis of these pathogens...
CHIR-AB1 is a newly identified avian immunoglobulin (Ig) receptor that includes both activating and inhibitory motifs and was therefore classified as a potentially bifunctional receptor. Recently, CHIR-AB1 was shown to bind the Fc region of chicken IgY and to induce calcium mobilization via association with the common gamma-chain, a subunit that transmits signals upon ligation of many different...
