Species of Origin
His Tag (N-term)
Lyophilized from a 0.2 µm filtered solution of PBS, pH 7.4.
>98% as determined by SDS-PAGE analysis.
The protein has a calculated MW of 9.49 kDa.
The protein migrates as 11 kDa under reducing condition (SDS-PAGE analysis).
Measure by its ability to chemoattract BaF3 cells transfected with human CXCR5. The ED₅₀ for this effect is <20 ng/mL.
<0.1 EU per 1 μg of the protein by the LAL method.
C-X-C motif chemokine 13 (CXCL13) also named B lymphocyte chemoattractant (BLC), which is a chemokine of the intercrine alpha family. CXCL13 is a 7.9kDa protein containing 72 amino acid residues. CXCL13 is a chemotaxis for B lymphocyte. CXCL13 induces the cell proliferation though the AKT signal pathway which plays a key role intestinal cancer model. CXCL13 /CXCR5 axis is highly existed in gut, spleen and lymph nodes.
