Anti-Eotaxin/CCL11 Antibody Picoband® Fluoro594 Conjugated

CCL11 (Chemokine (C-C motif) ligand 11), also known as Eotaxin, is a small cytokine belonging to the CC chemokine family. Eotaxin selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergic responses. The effects of Eotaxin are mediated by its binding to a G-protein-linked receptor known as a chemokine receptor. Chemokine receptors for which Eotaxin is a ligand include CCR2, CCR3 and CCR5. However, it has been found that eotaxin-1 (CCL11) has high degree selectivity for its receptor, such that they are inactive on neutrophils and monocytes, which do not express CCR3. The gene for human Eotaxin is encoded on three exons and is located on chromosome 17q12.

E. coli-derived human Eotaxin recombinant protein (Position: G24-P97) . Human Eotaxin shares 61.6% and 63% amino acid (aa) sequence identity with mouse and rat Eotaxin, respectively.

Synthesized in liver and selectively concentrated in bone matrix. Secreted in plasma. It is also found in dentin in much higher quantities than other plasma proteins.

In response to the presence of allergens, this protein ly promotes the accumulation of eosinophils, a prominent feature of allergic inflammatory reactions. Binds to CCR3.
