Human CCR8 Antibody Summary

Species Reactivity
Detects human CCR8. Neutralizes the bioactivity of human CCR8 and specifically stains human CCR8-transfected cell lines but not with the parent cell lines.
Monoclonal Rat IgG2B Clone # 191704
Protein A or G purified from hybridoma culture supernatant
BaF3 mouse pro-B cell line transfected with human CCR8
Accession # P51685
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.


Recommended Concentration
Flow Cytometry
0.25 µg/106 cells
See below
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
Measured by its ability to neutralize CCL1/I‑309/TCA‑3-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR8. The Neutralization Dose (ND50) is typically 0.01-0.05 µg/mL in the presence of 20 ng/mL Recombinant Human CCL1/I‑309/TCA‑3.

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.

Flow Cytometry Detection of CCR8 antibody in Human Blood antibody by Flow Cytometry. View Larger

Detection of CCR8 in Human Blood by Flow Cytometry. Human peripheral blood cells were stained with (A) Rat Anti-Human CCR8 Monoclonal Antibody (Catalog # MAB1429) or (B) isotype control antibody (Catalog # MAB0061) followed by anti-Rat IgG APC-conjugated Secondary Antibody (Catalog # F0113) and Mouse anti-Human CD14 PE-conjugated Monoclonal Antibody (Catalog # FAB3832P).

Neutralization Chemotaxis Induced by CCL1/I‑309 and Neutralization by Human CCR8 Antibody. View Larger

Chemotaxis Induced by CCL1/I‑309 and Neutralization by Human CCR8 Antibody. Recombinant Human CCL1/I-309 (Catalog # 272-I) chemoattracts the BaF3 mouse pro-B cell line transfected with human CCR8 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 CCL1/I-309 (20 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Human CCR8 Monoclonal Antibody (Catalog # MAB1429). The ND50 is typically 0.01-0.05 µg/mL.

Background: CCR8

CCR8 (C-C chemokine receptor 8; previously called CKR-L1 or TER1 and designated CD198) is a 41-43 kDa member of the GPCR 1 family of transmembrane proteins.  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.  Human CCR8 is a 7-transmembrane protein that is 355 amino acids (aa) in length.  It contains a 35 aa N-terminal extracellular domain plus a 51 aa C-terminal cytoplasmic tail. Over aa sequences 1-33 and 92-105 collectively, human and mouse CCR8 share 64% aa sequence identity.

  1. Are there special considerations for Flow Cytometry using Human CCR8 Antibody, Catalog # MAB1429 and FAB1429?

    • The staining with this antibody is temperature dependent;  it will stain at 4 C and room temperature, however, staining is stronger at 37 C.

Human CCR8 Antibody
By Peter Brams on 11/16/2019
Application: Flow Sample Tested: CHO Chinese hamster ovary cell line Species: Human CCR8 in hamster and human cells, Human, Rat

We ran standard FACS staining on human CCR8 transfected CHO and HEK293 cells. The antibody did not bind specifically, at all. Standard controls, including other antibodies, worked. We did the experiment with and without a N'terminal tag; same results.
