A polyclonal antibody from goat specific for LBP has been pre-coated onto 96-well plates. Standards (Expression system for standard: NSO; Immunogen sequence: A26-V481) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for LBP is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human LBP amount of sample captured in plate.\u003cbr\u003e\nLipopolysaccharide binding protein is a protein that in humans is encoded by the LBP gene. This gene is mapped to 20q11.23. LBP is a soluble acute-phase protein that binds to bacterial lipopolysaccharide (or LPS) to elicit immune responses by presenting the LPS to important cell surface pattern recognition receptors called CD14 and TLR4. It is present in the cerebrospinal fluid of patients with pneumococcal meningitis. The protein encoded by this gene is involved in the acute phase immunologic response to gram-negative bacterial infections. LBP is made in the liver during the acute phase of infections and is thought to function as a carrier for LPS and to help control LPS-dependent monocyte responses.\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\nLipopolysaccharide-binding protein (LBP) also known as LPS-binding protein is an acute-phase protein that plays a critical role in the immune response to Gram-negative bacterial infections. This protein weighing approximately 60kDa is primarily expressed in the liver and found in the serum. LBP binds to lipopolysaccharides (LPS) which are components of the outer membrane of Gram-negative bacteria facilitating the transfer of LPS to CD14 receptors on immune cells. This transfer enhances the recognition of bacterial endotoxins triggering an immune response.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nLBP serves a significant role in enhancing the sensitivity of the immune system to bacterial endotoxins. It does not form a permanent part of a larger complex but works closely with other molecules like CD14 and MD-2 an accessory protein of the TLR4 receptor to mediate the innate immune response. By efficiently binding LPS LBP aids in transporting these molecules to cell surface receptors accelerating the detection and subsequent response to infections.\u003cbr\u003e\nPathways\u003cbr\u003e\nLBP is heavily involved in the TLR4 signaling pathway which is important for the detection and response to Gram-negative bacterial infections. Through this pathway LBP and associated proteins such as CD14 and MD-2 help activate TLR4 triggering downstream NF-κB signaling. This activation leads to the production of pro-inflammatory cytokines and an upsurge in antimicrobial activities fortifying the body's defenses against bacterial invasion.\u003cbr\u003e\nEnhanced LBP levels have been associated with sepsis a severe systemic response to bacterial infections which can often lead to septic shock. Given its pivotal role in recognizing bacterial endotoxins LBP is important in identifying infections making it a potential prospect for therapeutic targeting. Additionally its interaction with CD14 means that alterations in LBP function or expression levels might contribute to immune dysregulation seen in inflammatory diseases such as Crohn's disease where immune responses to gut microbiota play a central role.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843627110569,"sku":"ab213805","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab213805","provider":"Iright","version":"1.0","type":"link"}
