چکیده

Monoclonal antibodies (Mabs) were produced against chicken IgY purified from egg yolks. Purity of the IgY was established using immunoelectrophoresis and reducing and non-reducing polyacrylamide gel electrophoresis. Five stable hybrid clones were characterized and Mabs, all belonging to IgG1 isotype, were found to bind to the IgY heavy chain in Western blots. These clones did not cross-react with IgM in enzyme-linked immunosorbent assay (ELISA). One of the Mabs was used as a capture antibody in ELISA for estimation of IgY purified from egg yolk by different methods. Caprylic acid precipitation method gave the highest recovery of IgY and with high purity.

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...

Characterization of IgY antibodies, developed in hens, directed against camel immunoglobulins

Chicken egg yolk antibodies (IgY) against camel immunoglobulins were generated and their specificity was shown by double immunodiffusion, immunoelectrophoresis, and Western blotting. Anti camel antibodies specifically react to camel antibodies in immunodiffusion and immunoelectrophoresis were demonstrated. Western blotting revealed that IgY antibodies recognize the heavy chain in a number of ma...
