Product Overview
This rabbit polyclonal antibody targets fractalkine (gene CX3CL1) in human samples and is validated for Western blot. The predicted molecular weight is 42.2 kDa, and the supplier reports an observed band at about 90–100 kDa.
Fractalkine (CX3CL1) is the only member of the CX3C chemokine family. It exists as a membrane-anchored adhesion molecule on endothelial cells and neurons and as a soluble chemoattractant after cleavage. Acting through CX3CR1, it guides monocyte, NK cell and T-cell adhesion and migration, and it mediates neuron-microglia communication in the brain.

|---|
Samples with a confirmed band (WB): recombinant human Fractalkine protein.
Recommended loading (WB): 20–40 µg of total protein per lane.
Immunogen
Synthetic peptide from the N-terminal region of human CX3CL1.
Reactivity Notes
The supplier lists reactivity with human. UniProt places fractalkine in the cell membrane. Tissue expression noted by UniProt (human): Expressed in the seminal plasma, endometrial fluid and follicular fluid (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
