Recombinant Human Eotaxin-3/CCL26
CCL26 is novel CC family chemokine, also known as TARC (thymus and activation regulated chemokine). It is encoded by CCL26 gene, which is located on Chr.7 in humans, and ubiquitously expressed at low levels in various tissues including heart and ovary. CCL26 elicits its effects activity by binding to the cell surface chemokine receptor CCR3, and chemotactic for eosinophils and basophils.

Formulation |
Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. |
|
Reconstitution |
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. |
