APPLICATION

Application Note

Chemokine C-X3-C-Motif Ligand 1 (CX3CL1) also known as fractalkine is a large cytokine protein of 373 amino acids, it contains multiple domains and is the only known member of the CX3C chemokine family. Soluble CX3CL1 potently chemoattracts T cells and monocytes, while the cell-bound chemokine promotes strong adhesion of leukocytes to activated endothelial cells, where it is primarily expressed. Thus, chemotaxis assay used 24-well microchemotaxis system was undertaken to detect the chemotactic effect of CX3CL1 on the human monocytic cell line THP-1. Briefly, THP-1 cells were seeded into the upper chambers (150 μl cell suspension, 1x10⁶ cells/ml in RPMI-1640 with FBS free) and SLC (15. 625 ng/ml, 31. 25 ng/ml, 62. 5 ng/ml and 125 ng/ml diluted separately in serum free RPMI-1640) was added in lower chamber with a polycarbonate filter (8um pore size) used to separate the two compartments. After incubation at 37ºC with 5% CO₂ for 1h, the filter was removed, then cells in low chamber were observed by inverted microscope at low magnification (×100) and the number of migrated cells were counted at high magnification (×400) randomly. And CX3CL1 is able to induce migration of THP-1 cells.

The chemotactic effect of GTX00363-pro Rat CX3CL1 protein (active).
Upper: (A) THP-1 cells were seeded into the upper chambers and serum free RPMI-1640 without CX3CL1 was added in lower chamber, then cells in lower chamber were observed at low magnification (×100) after incubation for 1hr.
(B) THP-1 cells were seeded into the upper chambers and serum free RPMI-1640 with 31.25 ng/ml CX3CL1 was added in lower chamber, then cells in lower chamber were observed at low magnification (×100) after incubation for 1hr.
Lower: The number of migrated cells were counted at high magnification (×400) randomly (five fields for each filter).
