Product OverviewDengue IgG/IgM And NS1 Combo Rapid Test Cassette    IDEC-425  It is widely distributed throughout the tropical and subtropical areas of the world,1 and causes up to 100 million infections annually.2 Classic Dengue infection is characterized by a sudden onset of fever, intense headache, myalgia, arthralgia and rash. Primary Dengue infection causes IgM antibodies to increase to a detectable level in 3 to 5 days after the onset of fever. IgM antibodies generally persist for 30 to 90 days.3 Most Dengue patients in endemic regions have secondary infections,4 resulting in high levels of specific IgG antibodies prior to or simultaneous with IgM response.5 Therefore, the detection of specific anti-Dengue IgM and IgG antibodies can also help to distinguish between primary and secondary infections. NS1 is one of 7 Dengue Virus non-structural proteins which are thought to be involved in viral replication. NS1 exists as a monomer in its immature form but is rapidly processed in the endoplasmic reticulum to form a stable dimer. A small amount of NS1 remains associated with intracellular organelles where it is thought to be involved in viral replication. The rest of NS1 is found either associated with the plasma membrane or secreted as a soluble hexadimer. NS1 is essential for viral viability but its precise biological function is unknown. Antibodies raised in response to NS1 in viral infection can cross react with cell surface antigens on epithelial cells and platelets and this has been implicated in the development of Dengue Hemorrhagic fever. The Dengue Combo Rapid Test Cassette (Whole Blood/Serum/Plasma) is a rapid test that utilizes a combination of NS1 antigen, IgG and IgM antibodies of dengue virus in human whole blood, serum or plasma.Package Size: 10t/kit
