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.

The results reveal that two energy transfer paths (i. e.β-PEB→α/β-PCB and β-PEB→α/βPCB′) with time constants of 50ps and 200ps, respectively, exist in R-PC monomers, and that α/β-PCB′chromophores are the terminal emitting acceptors with fluorescence lifetimes of 1150 ps. The experimental results of time-resolved fluorescence spectroscopy in case of R-PC trimers exhibit that the corresponding energy transfer processes are faster in R-PC trimers than in R-PC monomers, with time constants being 45ps, 165 ps and 920ps.
