Detects mouse Fractalkine in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant human (rh) Fractalkine and recombinant rat Fractalkine, 20% cross-reactivity with rhMCP-1, and 10% cross-reactivity with rhEotaxin is observed.
Polyclonal Goat IgG
E. coli-derived recombinant mouse CX3CL1/Fractalkine Leu22-Lys105 Accession # O35188
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Recombinant Mouse CX3CL1/Fractalkine Full Length
Measured by its ability to neutralize CX3CL1/Fractalkine-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CX3CR1. The Neutralization Dose (ND50) is typically 0.3-1.5 µg/mL in the presence of 30 ng/mL Recombinant Mouse CX3CL1/Fractalkine aa 25‑105.
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 Mouse CX3CL1/Fractalkine Antibody. Recombinant Mouse CX3CL1/Fractalkine (Catalog # 571-MF) chemoattracts the BaF3 mouse pro‑B cell line transfected with human 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 Mouse CX3CL1/Fractalkine (30 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse CX3CL1/Fractalkine Chemokine Domain Antigen Affinity-purified Polyclonal Antibody (Catalog # AF472). The ND50 is typically 0.3-1.5 µg/mL.

CX3CL1/Fractalkine is a transmembrane adhesion protein with a chemokine domain separated from the membrane by a mucin stalk. It is upregulated on many cell types during inflammation. The chemokine and mucin regions can be shed as a soluble chemokine that signals through the receptor CX3CR1. During extravasation, membrane-bound CX3CL1 traps leukocytes, then is cleaved to allow diapedesis. Soluble CX3CL1 protects neurons from microglial neurotoxicity, recruits macrophages for wound healing, recruits osteoclast precursors for bone resorption, and contributes to pathogenesis in coronary artery disease.
