Recombinant Rat Eotaxin/CCL11 (Rat Eotaxin/CCL11)
CCL11 is a potent eosinophil chemoattractant that was originally purified from bronchoalveolar lavage fluid of guinea pigs sensitized by aerosol challenge with ovalbumin. CCL11 also shows high aa sequence identity to members of the MCP family. CCL11 is chemotactic for eosinophils, but not mononuclear cells or neutrophils. CCL11 mRNA is expressed in a variety of tissues. The expression of CCL11 mRNA is induced in cultured endothelial cells in response to IFN-gamma. In addition, CCL11 mRNA is also induced in response to the transplantation of IL-4-secreting tumor cells. The CC chemokine receptor 3 (CCR3) has been identified as a specific human CCL11 receptor.

Sterile Filtered White lyophilized (freeze-dried) powder.
> 96% by SDS-PAGE and HPLC analyses.
The biological activity determined by a chemotaxis bioassay using purified eosinophils is in a concentration range of 0.1-1.0 μg/mL. Fully biologically active when compared to standard.
< 1.0 EU per 1μg of the protein by the LAL method.
Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.
