Product details:
Human LBP ELISA Kit (LPS Binding Protein) ab279407 is a rapid single-wash 90-min Sandwich ELISA to measure Human LBP (LPS Binding Protein)in cell culture media, citrate plasma, EDTA plasma, heparin plasma, serum. This SimpleStep sensitivity is 6.79 pg/mL.
How the assay works
Human LBP (LPS Binding Protein)SimpleStep ELISA
employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA
plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA
protocol summary in the image section for further details.
Assay Specificity
Our SimpleStep ELISA
kits use recombinant monoclonal antibodies rigorously validated to ensure the highest level of consistency and reproducibility, improved sensitivity and specificity and ease of scalability and security of supply.
Please refer to our protocol booklet for more details.

LBP (LPS Binding Protein) is an acute phase protein involved in the cellular response to gram-negative bacterial infections. LBP binds to LPS protein expressed on gram-negative bacteria and elicits a response by engaging with pattern recognition receptors, CD14 and TLR4. LBP is essential for the initial response to gram-negative bacterial infection but not for the downstream stages.

Lipopolysaccharide-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.
Biological function summary
LBP 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.
Pathways
LBP 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.
Enhanced 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.
