Abstract
Hemagglutinin protein (HA) was considered to be the primary target for monoclonal antibody production. This protein not only plays an important role in viral infections, but can also be used to differentiate H5N1 virus from other influenza A viruses. Hence, for diagnostic and therapeutic applications, it is important to develop anti-HA monoclonal antibody (MAb) with high sensitivity, specificity, stability, and productivity. Nine unique Fab MAbs were generated from chimeric chicken/human Fab phage display library constructed from cDNA derived from chickens immunized with recombinant hemagglutinin protein constructed from H5N1 avian influenza virus (A/Vietnam/1203/04). The obtained Fab MAbs showed several characteristics for further optimization and development-three clones were highly specific to only H5N1 virus. This finding can be applied to the development of H5N1 diagnostic testing. Another clone showed neutralization activity that inhibited H5N1 influenza virus infection in Madin-Darby canine kidney (MDCK) cells. In addition, one clone showed strong reactivity with several of the influenza A virus subtypes tested. The conversion of this clone to whole IgG is a promising study for a cross-neutralization activity test.
