Fractalkine/CX3CL1 Protein, Human (Biotinylated, HEK293, His, Avi)

Fractalkine/CX3CL1 is a chemokine that acts as a ligand to CX3CR1 and the integrins ITGAV: ITGB3 and ITGA4: ITGB1. CX3CL1 promotes lung cancer cell migration and invasion through the Src/FAK signaling pathway. CX3CL1 plays an important role in immune response, inflammation, cell adhesion and chemotaxis. Fractalkine/CX3CL1 Protein, Human (Biotinylated, HEK293, His, Avi) is the recombinant human-derived Fractalkine/CX3CL1 protein, expressed by HEK293 , with C-Avi, C-10*His labeled tag.

Fractalkine/CX3CL1 is a chemokine that acts as a ligand to CX3CR1 and the integrins ITGAV: ITGB3 and ITGA4: ITGB1. CX3CR1-CX3CL1 signaling performs different functions in different tissue comparators, such as immune response, inflammation, cell adhesion, and chemotaxis. CX3CL1 regulates endothelial cell adhesion and migration and activates integrins through CX3Cr1-dependent and CXCr1-independent activation. CX3CL1 promotes lung cancer cell migration and invasion through the Src/FAK signaling pathway^[1][2][3].

Measured by its binding ability in a functional ELISA. Immobilized Human CX3CL1 antibody at 1μg/ml (100μl/well) can bind biotinylated CX3CL1. The ED₅₀ for this effect is 3.504 μg/mL.

Approximately 50-90 kDa, based on SDS-PAGE under reducing conditions, due to the glycosylation.

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 0.5 M NaCl, 6% trehalose, pH 8.0.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
