| Abstract: | An efficient alternative method to detect the presence of H5N1 virus based on surface plasmon resonance (SPR) and monoclonal antibody against Influenza A (H5N1) virus was proposed in this study. Samples of H5N1 influenza virus were tested and analyzed. The results showed:1) The good performance of SPR biosensor was based on the direct detection, real time record, and without any additional labeling. 2) The detection limit of the assay was found to be 104.44 TCID50/mL, which was lower than the limit of ELISA of 103.24 TCID50/mL. 3) The consumption of antibody in SPR test was 100-fold lower than that in ELISA test. Thus, in the future, with the development of high quality virus antigen and antibody production, the SPR biosensor system would become the most commonly applied and efficient approach for influenza A viruses diagnosis. |
