HEK293 cells transfected with hCX3CL1 (A) vs Irrelevant HEK293 transfectant cells (B) were stained with Mouse Anti-Human CX3CL1/Fractalkine Chemokine Domain Monoclonal Antibody (Catalog # MAB3652R) and eGFP isotype control antibody (Catalog # MAB002) followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

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.

Applications for Human CX3CL1/Fractalkine Antibody

Application

Recommended Usage

CyTOF-ready

Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.

Flow Cytometry

0.25 µg/10⁶ cells
Sample: HEK293 cell Line transfected with Human CX3CL1/Fractalkine

Neutralization

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.

Background: CX3CL1/Fractalkine

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.
