Application Notes:

Anti-mouse TLR4 clones SA15-21 and MTS510 recognize distinct epitopes and don’t cross block each other.8 Clone MTS510 binds to an epitope of TLR4/MD-2 that is lost after LPS stimulation.8 In addition to flow cytometric uses, the MTS510 antibody has also been used for immunoprecipitation, immunofluorescence, and blocking of LPS-induced stimulation.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤1.0 µg per million cells in 100 µl volume. For Western blotting, the suggested use of this reagent is 1.0 - 5.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.

Toll-like receptors are highly conserved from Drosophila to humans and share structural and functional similarities. They are type I transmembrane signaling receptors which activate the innate immune system in response to pathogen invasion. So far, at least 13 TLR members have been identified. The secretory protein, MD2, associates with cell-surface bound TLR4 (CD284) on monocytes, B cells and T cells. TLR4 has been recognized as critical for host recognition of bacterial LPS in conjunction with MD2.

Structure: Type I transmembrane protein complex
