| Abstract: | Objective] The aim is to develop the piezoelectric immunosensor to detect H9-subtype avian influenza virus(AIV).Method] The immunosensor was set up by self-assembling mercaptopmpionic acid(MPA) to be monolayer on the silver-coated electrode of quartz crystal and coupling the monoclonal antibody to H9 subtype AIV with N-ethy-N′-(3-dimethyl aminopropyl)carbodiimide hydrochloride(EDC) and N-hydroxysuccinimide(NHS).The immunosensor to detect H9 subtype AIV was established.Result] The results showed that the immunosensor displayed better specificity to H9 AIV and had no response to H5AIV and NDV when it was used for detection.The sensitivity test indicated the detection sensitivity for the H9 subtype AIV could reach 20-100 EID50.Conclusion] The research provided a foundation for further research on the immunosensor for detecting AIV and it could be a new approach to detect other viruses in animal husbandry. |
