Scientific Data Images for Human CCL28 Antibody

Chemotaxis Induced by CCL28 and Neutralization by Human CCL28 Antibody.

Chemotaxis Induced by CCL28 and Neutralization by Human CCL28 Antibody.

Recombinant Human CCL28 (717-VC) chemoattracts the BaF3 mouse pro-B cell line transfected with mouse CCR10 in a dose-dependent manner (orange line). Chemotaxis elicited by Recombinant Human CCL28 is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL28 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF717). Typically, 100 µg/mL will cause >50% neutralization in the presence of 2 µg/mL Recombinant Human CCL28.

Applications for Human CCL28 Antibody

Application
Recommended Usage

Western Blot

0.1 µg/mL
Sample: Recombinant Human CCL28 (Catalog # 717-VC)

Neutralization

Measured by its ability to neutralize CCL28-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR10. Typically 100 µg/mL will cause >50% neutralization in the presence of 2 µg/mL Recombinant Human CCL28.

Background: CCL28

Human CCL28 (CC chemokine ligand 28) is a novel CC chemokine identified by TBLASTN searches of the Human Genome Systems (HGS) and Genbank dbEst database using a human chemokine consensus sequence. Human CCL28 cDNA encodes a 127 amino acid (aa) residue precursor protein with a putative 22 aa residue signal peptide that is cleaved to produce the 105 aa residue mature protein. Human and mouse CCL28 are highly conserved, sharing 83% aa identity in their mature regions. Among CC chemokines, CCL28 shares the most homology with CCL27/CTACK. The mouse CCL28 gene has been mapped to the distal region of chromosome 13. Human and mouse CCL28 RNA expression was found to be highest in normal and pathologic colon with the protein being expressed by epithelial cells. Human CCL28 RNA was also present in normal and asthmatic lung tissues. The receptor for CCL28 has been identified as the CCR10 (GPR2 orphan receptor) which is also the receptor for CCL27/CTACK.
