abstract

background: the use of igys in a variety of methods in different areas of research, diagnostics, medical application and biotechnology should be considered widely. objectives: development of antibodies against extra cellular domain of influenza m2 (m2e) protein in egg yolk of laying hens. methods: a fusion construct harboring c-terminal of bovine heat shock protein 70 (hsp70) and influenza m2e coding genes was injected to laying hens. serum and egg yolk antibodies were screened for the presence of anti-m2e antibodies by indirect enzyme-linked immunosorbent assay (elisa). results: anti-m2e antibodies were detected in egg yolks and sera of injected hens from 13 and 7 days post injection (pi), with the peak titer detected on 41 and 35 days pi, respectively. conclusions: anti-m2e igy titers could be an index for expression potential of pcdna3.1-m2e-hspc-terminal construct in laying hens. this construct could be considered as a promising tool in production of anti-m2e polyclonal, monospecific igy antibodies. such anti-m2e antibodies could be exploited for influenza diagnostic and therapeutic measures.

Generation 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...

Fusion and sequence analysis of the influenza A (H9N2) virus M2e and C-terminal fragment of Mycobacterium tuberculosis HSP70 (H37Rv)

The present study was aimed to construct a fusion plasmid harboring the extracellular domain of the influenza A M2-protein (M2e), which was fused to the N-terminus of the truncated HSP70 (HSP70359–610) molecule as a new approach for future vaccine research against influenza A. The amplified fragments, M2e and HSP70359-610 genes, were gel-purified. The products were then single digested with Bam...

Cloning of the Gene Encoding M2e of Influenza Virus in B. subtilis

Background and Aims: The ectodomain of matrix protein of influenza virus is a weak immunogen that is highly conserved among all subtypes of influenza A virus. Tandem repeats of these genes along with linker were used to enhance immunogenicity of M2e protein and so it can be served as a universal vaccine in both humans and livestock. Materials and Methods: In this study, the sequences of extra-d...
