چکیده

ABsTRACT Producing polyclonal antibodies (IgY) in chickens has advantages over those obtained in other animal models, since they have been used as a tool for studying different proteins (NMDA glutamate receptor in our case, specifically the NR1 subunit). We produced specific antibo-dies against expression products by the alternative splicing of the gene encoding NMDA receptor NR1 subunit in adult rat brain. Three peptides corresponding to the splicing sites (N1, C1 and C2' cassettes) were designed, synthesised and used individually as antigens in hens. Specific immunoglobulins were purified from yolks. The antibodies were then used for purifying the NMDA receptor NR1 subu-nit using affinity chromatography coupling the three antibodies to the support.tografía de afinidad, a través del acople de los tres anticuerpos al soporte. REsumO A produção de anticorpos policlonais (IgY) em galinhas tem vantagens so-bre os obtidos em outros modelos ani-mais e eles têm sido usados como uma ferramenta para o estudo de proteínas diferentes (NMDA receptor de gluta-mato no nosso caso, especificamente a subunidade NR1). Nós produzimos an-ticorpos específicos contra produtos de expressão pela splicing alternativo do gene que codifica receptor NMDA subu-nidade NR1 no cérebro de ratos adultos. Três peptídeos correspondentes aos lo-cais de splicing (N1, C1 e C2' cassetes) foram concebidos, sintetizados e utiliza-dos individualmente como antígenos em galinhas. Imunoglobulinas específicas foram purificadas a partir de gemas. Os anticorpos foram então usados para puri-ficar o receptor NMDA subunidade NR1 utilizando cromatografia de afinidade, por meio da junção dos três anticorpos ao suporte.

Extraction and Purification of Anti-Proteinase 3 (PR3) Antibodies from Egg Yolk

Recently it has been reported, that immunoglobulin Y (IgY) can be used instead of polyclonal antibodies extracted from mammals (IgG) for the purpose of diagnosis and therapy. These antibodies are found to have better properties in terms of specificity and ease of large-scale production. In addition, IgY binds neither to mammalian complement or Fc-receptors nor does it interfere with rheumatoid ...

Production, Purification and Characterization of Chicken Egg Yolk Monoclonal Antibody Against Colonization factor antigen -1 of Enterotoxigenic Escherichia coli Causing Diarrhea

Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in both humans and animals. The contaminated food and water are the most common vehicles for ETEC infection. The colonization factor antigen (CFA-1) is a fimbriae protein that promotes adherence of the ETEC strain to the epithelium of the small intestine of the host. In this study IgY proteins were produced against the CFA-1 of ETEC in imm...
