Standards and samples are pipetted into the wells and the immobilized antibody captures MBL present in the samples. The wells are washed and biotinylated anti-Human MBL antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of MBL bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions--20°C, Appropriate long-term storage conditions--20°C, Storage information--20°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nMannan Binding Lectin often referred to as MBL is an important player in the innate immune system. It is known alternatively as mannose-binding lectin or mannan-binding protein. The mass of MBL is approximately 32 to 34 kilodaltons and it is primarily produced in the liver. MBL circulates in the bloodstream where it can recognize patterns on the surface of pathogens such as bacteria and viruses through its lectin-binding domain. This recognition leads to the activation of other components that play roles in immune response.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nMannan Binding Lectin serves a significant role in immune defense by binding to carbohydrate structures on pathogens. It is part of a complex known as the lectin pathway of the complement system one of three pathways that activate the complement system to enhance pathogen removal. MBL can activate through a series of proteases leading to opsonization cell lysis and inflammation which are vital responses to infection.\u003cbr\u003e\nPathways\u003cbr\u003e\nMannan recognition by MBL initiates the lectin pathway an essential component of the complement system. This pathway converges with the classical and alternative pathways to enhance the immune response. MBL works closely with MBL-associated serine proteases (MASPs) particularly MASP-1 and MASP-2 which cleave complement proteins resulting in pathogen opsonization and membrane attack complex formation. These actions are tightly regulated and ensure effective defense against invaders.\u003cbr\u003e\nDeficiencies or polymorphisms in MBL can lead to increased susceptibility to infections and developmental complications of the immune system. Individuals with low MBL levels may experience recurrent respiratory infections or other bacterial infections due to inadequate complement activation. Moreover variations in the MBL protein have connections with autoimmune diseases such as systemic lupus erythematosus where MBL levels might influence disease severity. In these conditions altered interactions with other immune proteins like C4 and C3 may contribute to pathological responses.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46855642677417,"sku":"ab193709","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab193709","provider":"Iright","version":"1.0","type":"link"}
