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.

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.

Related FAQs

What type of PE do you use in your conjugates?
We use R-PE in our conjugates.
Does staining at room temperature or even at 37°C help for checking chemokine receptors expression?

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.
