Scientific Data Images for Human CCL17/TARC Antibody

Chemotaxis Induced by CCL17/TARC and Neutralization by Human CCL17/TARC Antibody.

Chemotaxis Induced by CCL17/TARC and Neutralization by Human CCL17/TARC Antibody.

Recombinant Human CCL17/TARC (Catalog # 364-DN) chemoattracts the BaF3 mouse pro-B cell line transfected with human CCR4 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 CCL17/ TARC (0.01 µg/mL) is neutral-ized (green line) by increasing concentrations of Goat Anti-Human CCL17/TARC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF364). The ND50 is typically 0.3-1.5 µg/mL.
CCL17/TARC antibody in Human Spleen by Immunohistochemistry (IHC-P).

CCL17/TARC in Human Spleen.

CCL17/TARC was detected in immersion fixed paraffin-embedded sections of human spleen using Goat Anti-Human CCL17/TARC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF364) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm in lymphocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

Applications for Human CCL17/TARC Antibody

Application
Recommended Usage

Immunohistochemistry

5-15 µg/mL
Sample: Immersion fixed paraffin-embedded sections of human spleen

Western Blot

0.1 µg/mL
Sample: Recombinant Human CCL17/TARC (Catalog # 364-DN)

Neutralization

Measured by its ability to neutralize CCL17/TARC-induced chemotaxis in the BaF3 mouse pro-B cell line transfected with human CCR4. The Neutralization Dose (ND50) is typically 0.3-1.5 µg/mL in the presence of 0.01 µg/mL Recombinant Human CCL17/TARC.
Please Note: Optimal dilutions of this antibody should be experimentally determined.

Background: CCL17/TARC

CCL17 is a novel CC chemokine identified using a signal sequence trap method. CCL17 cDNA encodes a highly basic 94 amino acid (aa)residue precursor protein with a 23 aa residue signal peptide that is cleaved to generate the 71 aa residue mature secreted protein. Among CC chemokine family members, CCL17 has approximately 24-29% amino acid sequence identity with RANTES, MIP-1 alpha, MIP-1 beta, MCP-1, MCP-2, MCP-3, and I-309. The gene for human CCL17 has been mapped to chromosome 16q13 rather than chromosome 17 where the genes for many human CC chemokines are clustered. CCL17 is constitutively expressed in thymus, and at a lower level in lung, colon, and small intestine. CCL17 is also transiently expressed in stimulated peripheral blood mononuclear cells. Recombinant CCL17 has been shown to be chemotactic for T cell lines but not monocytes or neutrophils. CCL17 was identified to be a specific functional ligand for CCR4, a receptor that is selectively expressed on T cells.
