The potency of chicken egg yolk immunoglobulin (IgY) specific as immunotherapy to Mycobacterium tuberculosis infection
The aim of this study was to characterize of chicken egg yolk immunoglobulins (IgYs) specific as immunotherapy to Mycobacterium tuberculosis complex (MTBC) infection. Lohmann laying hens were immunized intramuscularly with antigenic of MTBC. Egg yolk was separated from egg white, and IgY antibody was then purified by multiple polyethylene glycols 6000 extraction and ammonium sulfate purificatio...
متن کاملGeneration of Egg Yolk Antibodies in Chicken ( IgY ) Against Influenza M 2 ( M 2 e ) Protein
Chicken egg yolk immunoglobulins (IgY) from immunized hens have considerable advantages for the production of polyclonal antibodies. It reacts with more epitopes and avoids the interference in immunological assays. Regarding the IgY aptitudes, this study was conducted to produce chicken IgY specific for influenza M2 (M2e) protein. Fusion construct harboring C-terminal of bovine heat shock prote...
متن کاملProductivity and some properties of immunoglobulin specific against Streptococcus mutans serotype c in chicken egg yolk (IgY).
Hens were immunized on thighs by using whole cells of Streptococcus mutans MT8148 serotype c strain as antigen through intramuscular (im) and subcutaneous (sc) routes to investigate the difference of immunization reactions and the changes in yolk antibody activities against antigen after initial immunization. Several properties of crude IgY were examined to evaluate the stability during food pr...

متن کاملPurification and Characterization of Chicken Egg Yolk Antibodies (IgY) Against Mastitis Causing Klebsiella pneumoniae
White leghorn hens were immunized intramuscularly with formalin killed Klebsiella pneumoniae cells to generate Klebsiella pneumoniae antibodies (IgY) in egg yolk. Booster injections of increasing concentrations of antigen were given to raise the antibody level in egg yolk. Amount of protein varied from 0.87 7.4mg/ml in egg yolk throughout the immunization period. The antibodies were partially p...
