Scientific Data Images for Human CCL11/Eotaxin Antibody

CCL11/Eotaxin antibody in Human Colon by Immunohistochemistry (IHC-P).

CCL11/Eotaxin in Human Colon.

CCL11/Eotaxin was detected in immersion fixed paraffin-embedded sections of human colon using Mouse Anti-Human CCL11/Eotaxin Monoclonal Antibody (Catalog # MAB320) at 15 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of epithelial and stromal cells.

Chemotaxis Induced by CCL11/Eotaxin and Neutralization by Human CCL11/Eotaxin Antibody.

Chemotaxis Induced by CCL11/Eotaxin and Neutralization by Human CCL11/Eotaxin Antibody.

Recombinant Human CCL11/Eotaxin (Catalog # 320-EO) 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 Goat Anti-Human CCL11/Eotaxin (5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CCL11/Eotaxin Monoclonal Antibody (Catalog # MAB320). The ND50 is typically 1-5 µg/mL.

Detection of CCL11/Eotaxin in Human Duodenum.

Formalin-fixed paraffin-embedded tissue sections of human duodenum were probed for Eotaxin mRNA (ACD RNAScope Probe, catalog # 438468; Fast Red chromogen, ACD catalog # 322750). Adjacent tissue section was processed for immunohistochemistry using mouse anti-human Eotaxin monoclonal antibody (R&D Systems catalog # MAB320) at 20ug/mL with overnight incubation at 4 degrees Celsius followed by incubation with anti-mouse IgG VisUCyte HRP Polymer Antibody (Catalog # VC001) and DAB chromogen (yellow-brown). Tissue was counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of epithelial and stromal cells.

Background: CCL11/Eotaxin

CCL11 is a potent eosinophil chemoattractant that was originally purified from bronchoalveolar lavage fluid of guinea pigs sensitized by aerosol challenge with ovalbumin. Microsequencing of the purified protein revealed the guinea pig CCL11 to be a member of the beta (CC) chemokine family of inflammatory and immunoregulatory cytokines. cDNA clones for guinea pig, mouse, and human CCL11 have been isolated. Human CCL11 cDNA encodes a 97 amino acid residue precursor protein from which the amino-terminal 23 amino acid residues are cleaved to generate the 74 amino acid residue mature human CCL11. At the protein sequence level, mature human CCL11 is approximately 60% identical to mature mouse and guinea pig CCL11. In addition, human CCL11 also shows high amino acid sequence identity to human MCP-1, 2, and 3. Human CCL11 is chemotactic for eosinophils, but not mononuclear cells or neutrophils. The CC chemokine receptor 3 (CCR3) has now been identified to be a specific human CCL11 receptor (1-3). CCR3 has also been shown to serve as a cofactor for a restricted subset of primary HIV viruses and binding of CCL11 to CCR3 inhibited infection by the HIV isolates (4).
