Description

Toll-like receptor 4 serves as a critical sentinel of the innate immune system, recognizing lipopolysaccharide from gram-negative bacteria and initiating inflammatory signaling cascades that shape both protective immunity and pathological inflammation. This pattern recognition receptor has become central to research spanning infectious disease, sepsis, atherosclerosis, and autoimmune conditions, making reliable detection tools essential for investigators working across these interconnected fields.

This recombinant monoclonal antibody against human TLR4, clone 2E10, offers the reproducibility that demanding immunological studies require. Because recombinant production ensures a sequence-defined antibody with consistent performance across lots, researchers can confidently compare results between experiments and build on previous findings without concerns about batch variation that can complicate longitudinal studies.

Flow cytometry validation demonstrates clear detection of TLR4 in HeLa cells, with testing performed using fixed and permeabilized cells at a 1:100 dilution. The overlay histogram shows distinct separation between the TLR4 signal and isotype control, confirming specific detection suitable for quantitative analysis of receptor expression levels. For flow cytometry applications, dilutions ranging from 1:50 to 1:200 provide flexibility to optimize signal intensity based on your specific experimental conditions and cell types.

The antibody is supplied in a glycerol-based PBS buffer optimized for long-term stability at -20°C or -80°C, supporting extended research programs. Whether investigating TLR4 signaling in cardiovascular inflammation, characterizing immune cell activation states, or studying host-pathogen interactions, this antibody provides a dependable tool for advancing understanding of innate immune recognition and its consequences in health and disease.

Target Background

Function

Cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MYD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Also involved in LPS-independent inflammatory responses triggered by free fatty acids, such as palmitate, and Ni(2+). Responses triggered by Ni(2+) require non-conserved histidines and are, therefore, species-specific. Both M.tuberculosis HSP70 (dnaK) and HSP65 (groEL-2) act via this protein to stimulate NF-kappa-B expression. In complex with TLR6, promotes sterile inflammation in monocytes/macrophages in response to oxidized low-density lipoprotein (oxLDL) or amyloid-beta 42. In this context, the initial signal is provided by oxLDL- or amyloid-beta 42-binding to CD36. This event induces the formation of a heterodimer of TLR4 and TLR6, which is rapidly internalized and triggers inflammatory response, leading to the NF-kappa-B-dependent production of CXCL1, CXCL2 and CCL9 cytokines, via MYD88 signaling pathway, and CCL5 cytokine, via TICAM1 signaling pathway, as well as IL1B secretion. Binds electronegative LDL (LDL(-)) and mediates the cytokine release induced by LDL(-). Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via TLR2, but also partially via this receptor. Activated by the signaling pathway regulator NMI which acts as damage-associated molecular patterns (DAMPs) in response to cell injury or pathogen invasion, therefore promoting nuclear factor NF-kappa-B activation.
