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 LPS in conjunction with MD2.Product Details

FC - Quality tested
- 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 ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Blue Laser (488 nm)
Green Laser (532 nm)/Yellow-Green Laser (561 nm)
- Application Notes
Anti-mouse TLR4 clones SA15-21 and MTS510 recognize distinct epitopes and don’t cross block each other.1 Clone MTS510 binds to an epitope of TLR4/MD-2 that is lost after LPS stimulation.1 Unlike MTS510, the binding of SA15-21 is not interrupted by LPS stimulation1. Clone SA15-21 is capable of recognizing TLR4 individually and when it is complexed with MD-2.
Additional reported applications (for the relevant formats) include: immunoprecipitation1 and inhibition of LPS-induced hepatocyte apoptosis2. The LEAF™ or Ultra-LEAF™ purified antibody is recommended for functional assays (contact our custom solutions team).
- Additional Product Notes
- BioLegend is in the process of converting the name PE/Cy7 to PE/Cyanine7. The dye molecule remains the same, so you should expect the same quality and performance from our PE/Cyanine7 products. Please contact Technical Service if you have any questions.
