Alias	protein/Z02898-Eotaxin-3_Human_CCL26_Human, Eotaxin3, also named CCL26 or SCYA26, is a novel human CC chemokine coded by CXCL26 gene at chromosome 7 in human. Recombinant Eotaxin3/CCL26 has been produced in insect cells using a baculovirus expression system and shown to contain 71 aa residues. Recombinant Eotaxin3/CCL26 is chemotactic for eosinophils and PHAactivated T cells. Eotaxin3/CCL26 induces calcium flux in eosinophils as well as in CCR3 transfected cells. Eotaxin3/CCL26 has also been shown to crossdesensitize cells to other CCR3 ligands. Both the 71 aa residue and 68 aa residue variants of recombinant Eotaxin3 have been expressed in E. coli and found to have equal potency in inducing chemotaxis of a human CCR3 transfected cell line. </td></tr><tr><th>M.W.</th><td colspan="7"> Approximately 8.4 kDa, a single non-glycosylated polypeptide chain containing 71 amino acid residues.</td></tr><tr><th>Purity</th><td colspan="7"> >97% by SDS-PAGE and HPLC analyses.</td></tr><tr><th>Endotoxin Level</th><td colspan="7"> Less than 0.2EU/ug of rHuEotaxin-3/CCL26 as determined by LAL method.</td></tr><tr><th>Specific Activity</th><td colspan="7"> Fully biologically active when compared to standard.
