The TF901 monoclonal antibody specifically binds to TLR4 (Toll-like receptor 4) which is also known as CD284. TLR4 is a 110 kDa type I transmembrane glycoprotein that belongs to the Toll-like receptor (TLR) family. TLR4 is expressed on monocytes, macrophages, granulocytes, dendritic cells and endothelial cells. TLR4 binds lipopolysaccharide (LPS) which is a major membrane component of Gram-negative bacteria. It thus acts as an innate immune recognition receptor against many pathogens. In association with MD-2, LPS binds to and signals through TLR4 receptors by MyD88-dependent and MyD88-independent pathways to induce the cellular production of proinflammatory cytokines. TF901 antibody binding is not influenced by the human TLR4 D299G/T399I polymorphism. Preincubation of TLR4-positive cells with the TF901 antibody blocks the subsequent binding of the HTA125 antibody which is also specific for human TLR4.
The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates.
