Chemokine Ligand 26 protein (CCL26) is a novel small cytokine belonging to the CC chemokine family which is involved in immunoregulatory and inflammatory processes. CCL26 is constitutively expressed in thymus; but only transiently expressed in phytohemagglutinin-stimulated peripheral blood mononuclear cells. It specifically binds and induces chemotaxis in T cells and elicits its effects by interacting with the chemokine receptor CCR4. CCL26; along with Eotaxin-1 and Eotaxin-2; selectively activates the CC chemokine receptor 3 (CCR3). The Eotaxin-3-CCR3 interaction may play an important role in allergic diseases such as atopic dermatitis and bronchial asthma. The full-length cDNA for CCL26 encodes a protein of 94 amino acids with a putative signal peptide of either 23 or 26 amino acid residues. Both the 71 and 68 amino acid residue variants of recombinant CCL26 demonstrate equal potency in inducing chemotaxis of a human CCR3-transfected cell line. Unlike most other CC chemokines; CCL26 maps to human chromosome 7q11.2; within 40 kilobases of the Eotaxin-2 loci. CCL26 and Eotaxin-2 are unique in that they are the only chemokines identified to date that map to chromosome 7.

< 1.0 EU per μg of the protein as determined by the LAL method.

Supplied as a 0.2 μm filtered solution of 20mM Tris-HCl, 1mM EDTA, 20% Glycerol, pH 9.0.

Recombinant Human CCL26 is produced by our E.coli expression system and the target gene encoding Thr24-Leu94 is expressed.
