Technical Data
TLR4 (Toll Like Receptor 4, CD284) (Biotin)
Toll-like receptors (TLR) are highly conserved throughout evolution and have been implicated in the innate defense to many pathogens. In Drosophila, toll is required for the anti-fungal response, while the related 18-wheeler is involved in antibacterial defenses. In mammals, TLR identified as type I transmembrane signaling receptors with pattern recognition capabilities, have been implicated in the innate host defense to pathogens. TLR4 has been identified next to MD-2 and CD14 as a receptor that is central to the innate immune response to lipopolysaccharides (LPS) of Gram-negative bacteria.

Suitable for use in Flow Cytometry, Functional Studies, ELISA, Immunofluorescence, Immunoprecipitation and Western Blot. Other applications have not been tested.

Recognizes human TLR4 (CD284) that is associated with MD-2. This clone is a TLR4 (CD284) function-blocking antibody that is useful for studies on the role of TLR4 (CD284) as a receptor for LPS induced cytokine production by TLR4 bearing cells. Species crossreactivity: canine, cynomolgus monkey, rhesus monkey and marmoset monkey.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
