No. FR97250 Product GS Description For immunological detection of antibodies directed against Dengue virus serotype 2 (most infected humans show serotype crossreactivity, irrespective of serotype) Background Dengue virus (flavoviridae) occurs in four distinct serotypes all transmitted by mosquitos (Aedes aegypti and Ae. albopictus). In humans the virus gives rise to Dengue fever, Dengue hemorrhagic fever and Dengue shock syndrome (DHF /DSS) occurring after sequential infections. All four serotypes can cause Dengue fever and DHF/ DSS, but severe disease seems to be associated with serotypes 2 and 3. Application Remove slide carefully from bag. Rehydrate slide for 2 min in PBS solution. Pipette test sample (approx. 20 µl per well) into individual well. Incubate for 30 min (in a moist chamber at room temperature). Wash 3x with PBS before applying secondary detection system. Interpretation of Results Approximately 20% of the cells on each well are Dengue virus infected and show positive reaction upon incubation with samples containing specific antibodies: virus forms cytoplasmic clusters. Noninfected cells (approx. 80% of cells) represent an internal negative control and should remain negative. A fourfold rise in IgM or IgG titers is considered as positive (cf. e.g. Gill et al, 2000) Stability Use immediately after opening of the sealed bag Storage At 2-8°C Special Note Although virus-infected VeroE6 cells are fixed, slides should be handled as potentially infectious! Quantity 50 tests (5 slides with 10 wells ea.) Individually sealed glass slides (GS) with fixed Dengue virus (serotype D2, New Guinea; from CAMR, UK) infected and non-infected cells.
