Antibodies to chicken gizzard myosin, subfragment 1, light chain 20, and light meromyosin were used to visualize myosin in stress fibers of cultured chicken cells. The antibody specificity was tested on purified gizzard proteins and total cell lysates using immunogold silver staining on protein blots. Immunofluorescence on cultured chicken fibroblasts and epithelial cells exhibited a similar st...
Interleukin-8(IL-8)/CXCL8 is a CXC-family chemokine that attracts lymphocytes to sites of tissue damage and plays a role in the inflammatory response and wound healing. Chicken chemotactic and angiogenic factor was referred to as chCXCLi2 and has been studied as one of human CXCL8 homologue for more than 20 years. However, no monoclonal antibodies (mAbs) that specifically detect chCXCLi2 have b...
Cellular transformation by oncogenic retroviruses encoding protein tyrosine kinases coincides with the tyrosine-specific phosphorylation of multiple protein substrates. Previous studies have shown that tyrosine phosphorylation of a protein of 120 kDa, p120, correlated with src transformation in chicken embryo fibroblasts. Additionally, we previously identified two phosphotyrosine-containing cel...
Laboratory detection of specific foot-and-mouth disease virus (FMDV) is routinely carried out by ELISA and RT-PCR. Identification and serotyping of FMDV by ELISA requires polyclonal antibodies raised in rabbits and guinea pigs. The polyclonal antibodies have certain disadvantages such as batch to batch variation, inconsistent yields of antibodies and limited quantity of serum obtained from indi...
Three monoclonal antibodies directed against chicken brush border myosin were used to study the possible function of myosin in microfilament organization and locomotion of chicken fibroblasts. These antibodies bind to distinct and separate epitopes on the heavy chain of chicken nonmuscle myosin and display differential effects of myosin filament formation and actin-myosin interaction (Citi, S.,...
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 chi...
Antibodies were raised against the sequence Glu-Glu-Glu-Glu-Tyr-Met-Pro-Met -Glu, which represents a part of the middle T antigen of polyomavirus that is considered to be important in inducing the phenotype of transformed cells. The antibodies reacted with native as well as denatured middle T antigens. In addition, the antibodies immunoprecipitated a cellular protein with an apparent molecular ...
Monoclonal antibodies (mAbs) have been produced against the chicken beta 1 subunit that affect integrin functions, including ligand binding, alpha subunit association, and regulation of ligand specificity. Epitope mapping of these antibodies was used to identify regions of the subunit involved in these functions. To accomplish this, we produced mouse/chicken chimeric beta 1 subunits and express...
To identify the protein-tyrosine kinases that are expressed during chicken embryonic development, a 10-day chicken embryo cDNA expression library was screened with anti-phosphotyrosine antibodies. Of the positive clones isolated, many encoded the same protein-tyrosine kinase, which we designate Cek1 (chicken embryo kinase 1). Its amino acid sequence suggests that the Cek1 protein is a transmemb...
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...
