Biolegend, 306503, Biotin anti-human CD184 (CXCR4) Antibody, 25μg

CD184, also known as fusin or CXCR4, is a 45 kD seven transmembrane G-protein-linked CXC chemokine receptor. CD184 is widely expressed on blood and tissue cells, including B and T cells, monocytes, macrophages, dendritic cells, granulocytes, megakaryocytes/platelets, lymphoid, myeloid precursor cells, endothelial cells, epithelial cells, astrocytes, and neurons, among other tissue cells. CD184 is the receptor for CXC chemokine SDF-1, mediates blood cell migration, and is involved in B lymphopoiesis and myelopoiesis, cardiogenesis, blood vessel formation, and cerebellar development. CXCR4 is also a coreceptor of X4 HIV-1 and an alternative receptor for some isolates of HIV-2.

Verified Reactivity: Human, Cynomolgus, Rhesus
Reported Reactivity: African Green, Baboon, Chimpanzee, Sooty Mangabey
Antibody Type: Monoclonal
Host Species: Mouse
Immunogen: CP-MAC-infected Sup-T1 cells
Formulation: Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide.
Preparation: The antibody was purified by affinity chromatography, and conjugated with biotin under optimal conditions.
Concentration: 0.5 mg/ml
Storage & Handling: The antibody solution should be stored undiluted between 2°C and 8°C. Do not freeze.
Application: 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 106 cells in 100 µl volume or 100 µl of 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 staining of paraffin-embedded tissue sections11, immunocytochemistry3, immunofluorescence microscopy2,6, and blocking of CD4-independent infection by HIV-2 and CD4-dependent infection by some T cell-tropic isolates of HIV-14,5. Clone 12G5 may not be suitable for Western blotting.10 The Ultra-LEAF™ purified antibody (Endotoxin <0.01 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. Nos. 306539 & 306540).

Q: How many biotin molecules are per antibody structure?
A: We don't routinely measure the number of biotins with our antibody products but the number of biotin molecules range from 3-6 molecules per antibody.
Q: Does staining at room temperature or even at 37°C help for checking chemokine receptors expression?
A: Due to continuous recycling of many chemokine receptors, it may be worthwhile to consider staining at room temperature or at 37°C if the staining at lower temperature (which can potentially reduce receptor turnover) is not optimal.
