Muscovy Duck fibroblast cells and embryo liquid infected with virus were carried out with Polystyrene LPA and were positive.

Development of latex agglutination test to detect antigens of Muscovy duck reovirus;

Objective To detect rheumatoid factor by applying latex agglutination test and rate nephelometry,then compare the diagnostic value of the two methods for patients with rheumatoid arthritis and obtain the optimal cut-off value of turbidmetric assay in diagnosing RA.

Enzyme linked immunosorbent assay(ELISA) and latex agglutination test were compared for detection of antibodies to Toxoplasma gondii in dogs and cats.

Objective To prepare the fiuid weak-positive quality control serum in the latex agglutination tests of Antistreptolysin-O antibody (ASO) and Rheumatoid factor (RF).

Comparison of latex agglutination test(LAT)and hameoagglutination inhibition test(HI) to detect antibodies against Japanese encephalitis virus in porcine sera;

The purified recombinant LHD-Sj23 protein coupled with latex microspheres was used to develope a latex agglutination test(LAT) for diagnosis of bovine schistosomiasis.

467 sera were detected with latex agglutination test(LAT) and double agar diffusion test(DADT),positive sera are 419 and negative sera are 48 with LAT.

Using the purified recombinant M protein of PRRSV as antigen,a latex agglutination test(LAT) was developed for detection of antibody against porcine reproductive and respiratory syndrome virus(PRRSV).

We built the method of LAT and indirect ELISA to detect egg yolk antibody of DHV-I, in order to detect immune level in duck conveniently and fast.

Monodisperse polystyrene latex particles were prepared via seed emulsion polymerization route, using polystyrene latex particles with an average grit size of 95.
