Chicken Egg Yolk antibodies (IgY) were raised in 24 week old white leg horn chickens against Streptococcus mitis (MTCC 2696). The chickens received Booster injections of increasing concentrations of antigen to raise the antibody level in egg yolk. The antibodies were purified from immunized chicken egg yolk by Poly ethylene Glycol (PEG) and Ammonium sulphate precipitation method and further pur...

Objective: The objective of the present investigation was to develop Chicken Egg Yolk antibodies as an alternative and affordable approach for diagnosis and treatment against dental caries in humans. Materials and Methods: Twenty four week old white leghorn chicken was immunized with formalin killed Streptococcus mutans (MTCC 890) to produce Egg Yolk antibodies (IgY). The amount of egg yolk ant...

Background: Single domain antibodies from camel heavy chain antibodies (VHH or nanobody), are advantages due to higher solubility, stability, high homology with human antibody, lower immunogenicity and low molecular weight. These criteria make them candidates for production of engineered antibody fragments particularly in transgenic animals. Objective: To study the development of transgenic ch...

BACKGROUND Allergy to hen's egg and meat contributes significantly to the manifestations of food allergy all over the world. OBJECTIVES This study was performed to assess the presence of hen's egg and meat specific IgE antibodies among patients investigated for various allergic disorders. METHODS This is a retrospective study performed at King Khalid University Hosptial, Riyadh. Data from 4...

Chicken integrin B1 eDNA and its sitedirected mutants were cloned into a mammalian expression vector and introduced into mouse NIH 3T3 cells. Stable transfectants expressing the chicken/31 subunit or its site-directed mutants were identified by immunostaining with antibodies specific for the chicken integrin/31 subunit. The chicken/~1 proteins were expressed predominately in the endoplasmic ret...

Chicken integrin beta 1 cDNA and its site-directed mutants were cloned into a mammalian expression vector and introduced into mouse NIH 3T3 cells. Stable transfectants expressing the chicken beta 1 subunit or its site-directed mutants were identified by immunostaining with antibodies specific for the chicken integrin beta 1 subunit. The chicken beta 1 proteins were expressed predominately in th...

Using antibodies prepared against a unique region (exon 22-24) of rat K(+)-Cl(-) cotransporter-2 (KCC2), we confirmed that the ~140-kDa KCC2 protein is exclusively expressed in rat brain, but in chicken, we observed strong reactivity not only with the ~140-kDa KCC2 protein in brain but also a slightly larger ~145-kDa protein in heart. In silico analysis showed that while exon 22 of KCC2 is uniq...

Myosin light chain kinase purified from chicken white skeletal muscle (Mr = 150,000) was significantly larger than both rabbit skeletal (Mr = 87,000) and chicken gizzard smooth (Mr = 130,000) muscle myosin light chain kinases, as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Km and Vmax values with rabbit or chicken skeletal, bovine cardiac, and chicken gizzard smooth...

The two chicken creatine kinases from brain and from muscle have been purified as well as the chicken hybrid enzyme. The brain and muscle enzymes from the rabbit have also been purified and compared to the chicken enzymes. There are significant differences in amino acid composition between the brain and muscle types; the hybrid enzyme has an intermediate composition. Peptide maps of the muscle ...
