Appearance Lyophilized powder. Formulation Lyophilized after extensive dialysis against PBS. Endotoxin Level <0.2 EU/μg, determined by LAL method. Reconstitution Reconstitute the lyophilized recombinant Rat Fractalkine/CX3CL1 (HEK293-expressed) (rRtFractalkine/CX3CL1) to 100 µg/mL using ddH2O or diluted with PBS. Storage & Stability Lyophilized recombinant Rat Fractalkine/CX3CL1 (HEK293-expressed) (rRtFractalkine/CX3CL1) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage. Shipping Room temperature in continental US; may vary elsewhere. Background Fractalkine is the only member of the CX3C chemokine family so far. It is expressed in many cell types such as hematopoietic cells, endothelial cells, epithelial cells, smooth muscle cells, dendritic cells, neurons, and fibroblasts. Fractalkine exists in two forms that have distinct cellular functions. The soluble form is a chemoattractant for cells expressing the CX3CR1 receptor. The membrane-bound form functions as an adhesion molecule that promotes adhesion and migration[1]. |
