Weitere Details:: CX3CL1 (fractalkine) is expressed on TNF-alpha and IL-1 activated endothelial cells (ECs). CX3CL1 can exist in 2 forms: as membrane- anchored or as a shed 95kD glycoprotein. The soluble CX3CL1 has potent chemoattractant activity for T cells and monocytes, and the cell surfacebound protein, which is induced on activated primary endothelial cells, promotes strong adhesion of those leukocytes. May play a role in regulating leukocyte adhesion and migration processes at the endothelium. Binds to CX3CR1. Recombinant protein corresponding to the extracellular domain of human CX3CL1 (aa25-339), fused at the C-terminus to a FLAG-tag, expressed in HEK293 cells. Molecular Weight: ~50kD (SDS-PAGE) Storage and Stability: Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
