Pneumophila serogroup 5 antibody to develop two immuo-colloidal gold tests respectively. Main works listed below as:1、Preparation and identification of polysaccharide antigen of L. pneumophila Bacteria of LP1 ~ 7,9 and 10 were cultured on yeast agar buffer activated carbon for three to five days at 37℃, 5%CO2. Protein-free polysaccharide antigens were obtained after harvest in cells, extraction, deproteinization, dialysis and other steps. Their immunogenicities were verified by ultraviolet spectrophotometer full-wavelength scanning and Western blotting.2、Preparation and identification of rabbit anti-LP1 antibodies and rabbit anti-LP5 antibody Rabbit anti-LP1 and anti-LP5 antibodies were purified after rabbits were immuned with antigens isolated as described above. The purities of both antibodies were above 80% and the titer of blood serum 1:32 tested by double antibody sandwich assay.3、Development of colloidal gold immunochromatographic assay kit The size of colloidal gold particles in the kit was 25nm. The optimal concentrations for antibodies were 30μg/ml and the sensitized concentrations of NC membrane were 5 mg/ml.
