CCR4 antibody

Catalog No. ABIN2689052

Product Details anti-CCR4 Antibody

Target: CCR4 (Chemokine (C-C Motif) Receptor 4 (CCR4))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This CCR4 antibody is un-conjugated

Application: Flow Cytometry (FACS)

Brand: BD Pharmingen™

Characteristics: The monoclonal antibody 1G1 reacts with CD194, also known as the human CC Chemokine Receptor type 4 (CCR4). CCR4 is expressed on activated Th2 cells, regulatory T cells, activated NK cells, basophils, monocytes and platelets. CCR4 is a seven-transmembrane, G-protein-coupled receptor, and is the specific receptor for CC chemokines, CCL22/MDC/Macrophage-Derived Chemokine and CCL17/TARC/Thymus and Activation-Regulated Chemokine. It has been reported that CCR4 mRNA is expressed mainly in the thymus and spleen. The human CCR4 gene has been mapped to chromosome 3p24. The purified form of this antibody has been reported not to be a neutralizing antibody. The immunogen used to generate the 1G1 hybridoma has been reported to be human CCR4 transfected L1.2 mouse lymphoma cells. Flow cytometric detection of CD194 (CCR4) on human peripheral lymphocytes. Human PBMC were stained with 0.25 μg of the purified Mouse Anti-Human CD194 (CCR4) antibody using a Biotin Goat Anti-Mouse Ig secondary antibody and with PE Streptavidin in conjunction with either a FITC Mouse Anti-Human CD4 antibody (Cat. No. 555346, left panel) or with a FITC Mouse Anti-Human CD8 antibody (Cat. No. 555366, right panel). The data reflects gating on lymphocytes, based on forward and side scattered light signals. The level of nonspecific staining was assessed by using purified mouse IgG1 (Cat. No. 555746) as an isotype control. The quadrant markers for the bivariate dot plots were set based on the isotype control.
