AA Sequence


Molecular Weight

Approximately 8.3 kDa

Biological Activity
The ED50 is <0.5 μg/mL as measured by CHO-K1/Gα15/hCXCR3 cells (human Gα15 and human CXCR3 stably expressed in CHO-K1 cells).

Lyophilized powder.


Lyophilized after extensive dialysis against PBS.

Endotoxin Level

<0.2 EU/μg, determined by LAL method.


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

Storage & Stability

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.


Room temperature in continental US; may vary elsewhere.


CXCL11 is produced by a variety of cells including leukocytes, fibroblasts, and endothelial cells upon stimulation with interferons (IFNs). Simultaneous stimulation of fibroblasts or endothelial cells with IFN-γ and interleukin-1β or the TLR3 ligand double-stranded RNA resulted in a synergistic increase of CXCL11 production. CXCL11 attracts activated T-helper 1 (Th1) lymphocytes and natural killer (NK) cells. Like CXCL9 or monokine induced by IFN-γ (Mig) and CXCL10 or IFN-γ–inducible protein-10 (IP-10), CXCL11 signals through CXC chemokine receptor 3 (CXCR3)[1].

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
