Production of an egg yolk antibody against Parietaria judaica 2 allergen.
Specific antibodies are essential tools for studying proteins as well as for diagnostic research in biomedicine. The egg yolk of immunized chicken is an inexpensive source of high-quality polyclonal antibodies. The 12-kDa Parietaria judaica 2 allergen was expressed as a fusion protein and was used to immunize Leghorn chickens. In this paper, we show, using 2-dimensional gel electrophoresis and ...
متن کاملProduction of Specific Egg Yolk Antibody (IgY) against Cryptosporidium parvum Oocysts
ABSTRACT Background and Objectives: Cryptosporidium parvum is a coccidian protozoan that causes diarrhea in immunocompromised humans and newborn animals. The severity of the disease depends on the immunological status of the affected. Cryptosporiosis can have lethal effects on immunocompromised individuals such as AIDS patients. About 10% of...
متن کاملLipid nanoparticles as delivery vehicles for the Parietaria judaica major allergen Par j 2
Parietaria pollen is one of the major causes of allergic reaction in southern Europe, affecting about 30% of all allergic patients in this area. Specific immunotherapy is the only treatment able to modify the natural outcome of the disease by restoring a normal immunity against allergens. The preparation of allergen-solid lipid nanoparticles as delivery vehicles for therapeutic proteins, P. jud...
متن کاملIdentification of an immunodominant IgE epitope of the Parietaria judaica major allergen.
Par j 1.0101 is one of the two major allergens of the Parietaria judaica (Pj) pollen, and its three-dimensional structure was built by three-dimensional structural homology modeling. The resultant model was used to identify putative IgE binding regions. Western blot analysis of gene fragmentation products showed that the 1 to 30 region was capable of binding specific IgE from a pool of sera (n ...
متن کاملcDNA cloning, expression and primary structure of Par jI, a major allergen of Parietaria judaica pollen.
A 659 bp cDNA clone** coding for an allergen of Pj pollen has been isolated from a lambda gt11 library, and its DNA sequence determined. The cDNA insert showed an open reading frame of 429 bp coding for an allergenic protein of 14,866 Da and a deduced amino acid sequence containing 143 residues. The expressed recombinant protein represented the major allergen Par jI since it reacted with 95% of...
