Design another set of specific primers, of which upstream and downstream primers were located in the two sides of the cleavage site respectively, to develop the one-step RT-PCR method for detecting H5 and H9 subtypes of AIV. Identify the sensitivity of the developed one-step RT-PCR method by detecting 2 AIV strains of H5 subtype and 3 AIV strains of H9 subtype, and the specificity by detecting the RNAs of NDV, IBV and IBDV as well as analogue detection using computer software.

Fluorescein isothiocyanate labeled polyclonal goat antihuman immunoglobulin antibody was added, and flow cytometer was used to detect bead-platelet-associated autoantibodies-antihuman immunoglobulin antibody complex. Results The fluorescene ratio of four monoclonal antibodies was significantly different (P.01) between the idiopathic thrombocytopenic purpura patients and either the non-ITP patients or the normal controls. If the upper limit of normal control was set as cutoff value, ratios of greater than 1.37, 1.24, 1.48 and 1.19 were considered positive for the four monoclonal antibodies respectively. The flow cytometric bead assay had an overall sensitivity of 73.17% and a specificity of 94.29%. The overall sensitivity was significantly higher (P.05) than that of modified indirect MAIPA and that of using single antibody.
