Detects CCL26/Eotaxin‑3 in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross-reactivity with recombinant human (rh) Eotaxin, recombinant mouse (rm) Eotaxin, rhEotaxin-2, and rmEotaxin-2 is observed.
Polyclonal Goat IgG
E. coli-derived recombinant human CCL26/Eotaxin‑3 Thr24-Leu94 Accession # Q9Y258
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Immersion fixed paraffin-embedded sections of human colon subjected to Antigen Retrieval Reagent-Basic (Catalog # CTS013)
Measured by its ability to neutralize CCL26/Eotaxin‑3-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR3. The Neutralization Dose (ND50) is typically 10-25 µg/mL in the presence of 1 µg/mL Recombinant Human CCL26/Eotaxin‑3.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Detection of Human CCL26/Eotaxin‑3 by Western Blot.
Western blot shows lysates of HUVEC human umbilical vein endothelial cells untreated (-) or treated (+) with 100 U/mL Recombinant Human IL‑4 (Catalog # 204-IL) for 24 hours. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human CCL26/Eotaxin‑3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF653) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for CCL26/ Eotaxin‑3 at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Chemotaxis Induced by CCL26/Eotaxin‑3 and Neutralizatio by Human CCL26/Eotaxin‑3 Antibody.
Recombinant Human CCL26/Eotaxin‑3 (Catalog # 346‑E3) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR3 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Human CCL26/Eotaxin‑3 (1 µg/mL) is neutralized (green line) by increasing concentrations of Human CCL26/Eotaxin‑3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF653). The ND50 is typically 10‑25 µg/mL.

Eotaxin-3, also named CCL26 or SCYA26, is a novel human CC chemokine that maps to chromosome 7q11.2, within 40 kilobases of the Eotaxin-2 loci. Eotaxin‑3/CCL26 has been shown to be constitutively expressed in the heart and ovary. In addition, low levels of Eotaxin-3/CCL26 expression can also be detected in various tissues. The expression of Eotaxin-3/CCL26 in vascular endothelial cells has been shown to be up-regulated by IL-13 and IL-4.
Eotaxin-3/CCL26 cDNA encodes a 94 amino acid (aa) residue protein with a putative signal peptide of either 23 or 26 aa residues. Recombinant Eotaxin-3/CCL26 has been produced in insect cells using a baculovirus expression system and shown to contain 71 aa residues. Recombinant Eotaxin-3/CCL26 is chemotactic for eosinophils and PHA-activated T cells. Eotaxin-3/CCL26 induces calcium flux in eosinophils as well as in CCR3-transfected cells. Eotaxin-3/CCL26 has also been shown to cross-desensitize cells to other CCR3 ligands. Both the 71 aa residue and 68 aa residue variants of recombinant Eotaxin-3 have been expressed in E. coli and found to have equal potency in inducing chemotaxis of a human CCR3-transfected cell line.
