Controls or test samples are added to the wells and incubated. Following washing, a horseradish peroxidase (HRP) labelled anti-Human IgA conjugate is added to the wells, which binds to the immobilized Influenza virus A-specific antibodies. TMB is then catalyzed by the HRP to produce a blue color product that changes to yellow after adding an acidic stop solution. The density of yellow coloration is directly proportional to the amount of Influenza virus A IgA sample captured in plate.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nInfluenza Virus A IgA is an immunoglobulin that specifically recognizes and binds to the influenza virus particularly the Influenza A virus which includes subtypes like H1N1. This immunoglobulin plays an important role in the immune response by preventing the virus from invading mucosal tissues. It weighs approximately 150 kDa and is mainly expressed along mucosal surfaces such as the respiratory and gastrointestinal tracts. Also referred to as can IgA HA and IgA pos it serves as an important indicator in evaluating immune protection against the Influenza A virus.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nImmunoglobulin A (IgA) plays a critical role in the immune defense mechanisms against mucosal pathogens. It is a part of the mucosal immunological complex and contributes to the first line of defense. IgA is the most abundant type of immunoglobulin present in mucosal areas and assists in neutralizing viruses and preventing infection. It binds to the HA proteins on the viral surface blocking entry into host cells.\u003cbr\u003e\nPathways\u003cbr\u003e\nInfluenza virus A IgA is important in the mucosal immune response pathway. It interacts with other components of the immune system such as secretory component\/SC and polymeric Ig receptor\/pIgR which facilitate the transport of IgA across epithelial cells to mucosal surfaces. These interactions help form barriers against pathogens and participate in pathways like receptor-mediated endocytosis and transport across epithelial barriers.\u003cbr\u003e\nInfluenza virus A IgA is important for understanding influenza infection and related respiratory diseases. The presence and levels of this immunoglobulin identified through IgA ELISA tests are correlated with protection against influenza. It interacts closely with HA proteins of the influenza virus and its absence or insufficient levels may result in increased susceptibility to the influenza virus leading to severe respiratory illness.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843653423273,"sku":"ab108743","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab108743","provider":"Iright","version":"1.0","type":"link"}
