Toll-like receptors are type I transmembrane signaling receptors. They are primordial pathogen-recognition proteins that function as sentinels for the innate immune system. TLR4, also known as CD284, is a 110 kD protein which is expressed on monocytes/macrophages, endothelial cells, and at low levels on B cells and granulocytes. In association with a secretory molecule, MD2, TLR4 has been recognized as critical for host recognition of bacterial LPS. HTA125 antibody is useful for flow cytometric analysis and is able to block LPS-induced cytokine production.

- 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 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.

- Application Notes
-
Additional reported applications (for the relevant formats) include: immunohistochemical staining of acetone-fixed frozen sections4, immunofluorescence microscopy6, Western blotting10, and in vitro blocking of LPS-induced cytokine production2,3,7,9. This clone was tested in-house and does not work on formalin fixed paraffin-embedded (FFPE) tissue. For most successful immunofluorescent staining results, it may be important to maximize signal over background by using a relatively bright fluorochrome-antibody conjugate (Cat. No. 312806) or by using a high sensitivity, three-layer staining technique (e.g., including a biotinylated antibody (Cat. No. 312804) or biotinylated anti-mouse IgG second step (Cat. No. 405303), followed by SAv-PE (Cat. No. 405204). The Ultra-LEAF™ purified antibody (Endotoxin < 0.01 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 312813 & 312814).
