Detection of CX3CL1/Fractalkine in HEK293 Human Cell Line Transfected with Human CX3CL1/Fractalkine and eGFP by Flow Cytometry. NS0 cell line transfected with human CX3CL1/Fractalkine was stained with Mouse Anti-Human CX3CL1/Fractalkine Monoclonal Antibody (Catalog # MAB3652R, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin. View our protocol for Staining Intracellular Proteins.
Chemotaxis Induced by CX3CL1/Fractalkine and Neutralization by Human CX3CL1/Fractalkine Antibody. Recombinant Human CX3CL1/Fractalkine (Catalog # 365-FR) chemoattracts the BaF3 mouse pro-B cell line transfected with mouse CX3CR1 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CX3CL1/Fractalkine (100 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CX3CL1/Fractalkine Chemokine Domain Monoclonal Antibody (Catalog # MAB3652). The ND50 is typically 1-5 µg/mL.

CX3CL1, also known as Fractalkine, is a type I membrane protein in which a chemokine domain possessing a unique C-X3-C cysteine motif is tethered on a long mucin-like stalk. It can also be released as a soluble molecule upon proteolysis at a membrane proximal site.
