Human CCL28 Antibody Summary

Species Reactivity

Human

Specificity

Detects human CCL28 in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity with recombinant mouse CCL28 is observed.

Source

Polyclonal Goat IgG

Purification

Antigen Affinity-purified

Immunogen

E. coli-derived recombinant human CCL28
Ile23-Tyr127
Accession # Q9NRJ3

Formulation

Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied either lyophilized or as a 0.2 µm filtered solution in PBS.

Endotoxin Level

<0.10 EU per 1 μg of the antibody by the LAL method.

Label

Unconjugated

Applications

Recommended Concentration

Sample

Western Blot

0.1 µg/mL

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. The Neutralization Dose (ND₅₀) is typically 40-100 µg/mL in the presence of 4 µg/mL Recombinant Human CCL28.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Chemotaxis Induced by CCL28 and Neutralization by Human CCL28 Antibody. Recombinant Human CCL28 (Catalog # 717-VC) chemoattracts the BaF3 mouse pro-B cell line transfected with mouse CCR10 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin. Chemotaxis elicited by Recombinant Human CCL28 (4 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL28 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF717). The ND₅₀ is typically 40-100 µg/mL.

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.
