Molecular Weight

Approximately 8.9 kDa

Biological Activity
The ED50 is <150 ng/mL as measured by CHO-K1/Gα15/hCXCR1 cells (human Gα15 and human CXCR1 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.


Interleukin-8 induces the full pattern of responses observed in chemotactically stimulated neutrophils, i.e., activation of the motile apparatus and directional migration, expression of surface adhesion molecules, release of storage enzymes, and production of reactive oxygen metabolites[1]. Human recombinant IL-8 is potently angiogenic when implanted in the rat cornea and induced proliferation and chemotaxis of human umbilical vein endothelial cells[2].

  • Reconstitution Calculator

  • Dilution Calculator

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)
× = ×
