Measured by its ability to neutralize CX3CL1/Fractalkine-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CX3CR1. The Neutralization Dose (ND50) is typically 1-5 µg/mL in the presence of 100 ng/mL Recombinant Human CX3CL1/Fractalkine.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
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.
