Detection of Mouse and Rat CCR8 by Western Blot. Western blot shows lysates of mouse thymus tissue and rat thymus tissue. PVDF Membrane was probed with 0.5 µg/mL of Sheep Anti-Mouse/Rat CCR8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5997) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for CCR8 at approximately 41-43 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

CCR8 (C-C chemokine receptor 8; also CD198) is a 41‑43 kDa member of the GPCR #1 family of transmembrane proteins. Mouse CCR8 is expressed on vascular smooth muscle cells, monocytes, eosinophils, peritoneal macrophages, thymocytes, CD8+ T cells, Langerhans cells and neurons. CCL1/TCA3 and vMIP-1 are known agonists for CCR8. Mouse CCR8 is a 7-transmembrane protein that is 353 amino acids (aa) in length. It contains a 33 aa N-terminal extracellular domain plus a 50 aa C-terminal cytoplasmic tail. In mouse, CCR8 is N- and possibly O‑glycosylated, and known to be sulfated on Tyr14 and 15. The unusual nature of these posttranslational modifications may lead to anomalous migration in SDS-PAGE. There are two potential isoforms, one that shows a deletion of aa 103‑163, and another that shows a Met substitution for aa 125‑166. Over aa sequences 1‑33 and 92‑105 collectively, mouse CCR8 shares 64% and 85% aa identity with human and rat CCR8, respectively.
