The antibody solution should be stored undiluted at 4°C.
Application:
FC1 - Quality Tested IHC(Frozen)4*, IF6 * - *This application has been reported in the literature.
Recommended Usage:
Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For immunofluorescent staining, the suggested use of this reagent is ≤ 0.5 µg per 106 cells in 100 µl volume or per 100 µl whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
Application Notes:
Additional reported applications (for the relevant formats) include: immunohistochemical staining4 of acetone-fixed frozen sections, immunofluorescence microscopy6, and in vitro blocking of LPS-induced cytokine production2,3,7.9. 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 LEAF™ purified antibody (Endotoxin <0.1 EU/μg, Azide-Free, 0.2 μm sterile-filtered) is recommended for functional assays (Cat. No. 312807).

Human peripheral blood monocytes stained with HTA125 PE
Description:
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.
