Detection of CX3CL1/Fractalkine in NS0 Mouse Cell Line Transfected with His-tagged Human CX3CL1 by Flow Cytometry. NS0 mouse myeloma cell line transfected with His-tagged human CX3CL1 was stained with Mouse Anti-His Tag PE-conjugated Monoclonal Antibody (Catalog # IC050P) and either (A) Mouse Anti-Human CX3CL1/Fractalkine APC-conjugated Monoclonal Antibody (Catalog # IC365A) or (B) Mouse IgG1Allophycocyanin Isotype Control (Catalog # IC002A). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: CX3CL1/Fractalkine

CX3CL1, also known as Fractalkine and Neurotactin, is a novel chemokine identified through bioinformatics. CX3CL1 has a unique C-X3-C cysteine motif near the amino-terminus and is the first member of a fourth branch of the chemokine superfamily. Unlike other known chemokines, CX3CL1 is a type 1 membrane protein containing a chemokine domain tethered on a long mucin-like stalk. Human CX3CL1 cDNA encodes a 397 amino acid (aa) residue membrane protein with a 24 aa residue predicted signal peptide, a 76 aa residue chemokine domain, a 241 aa residue stalk region containing 17 degenerate mucin-like repeats, a 19 aa residue transmembrane segment and a 37 aa residue cytoplasmic domain. The extracellular domain of human CX3CL1 can be released, possibly by proteolysis at the dibasic cleavage site proximal to the membrane, to generate soluble CX3CL1. CX3CL1 mRNA has been detected in various tissues including the brain and heart. The expression of CX3CL1 was also reported to be up-regulated in endothelial cells and microglia by inflammatory signals. Membrane-bound CX3CL1 has been shown to promote adhesion of leukocytes. The soluble chemokine domain of human CX3CL1 was reported to be chemotactic for T cells and monocytes while the soluble chemokine domain of mouse CX3CL1 was reported to chemoattract neutrophils and T-lymphocytes but not monocytes.
