The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/200 - 1/400.
Use 1.2µg for 106 cells. ab170191-Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
Use 1µg for 106 cells.
High affinity receptor for the C-C type chemokines CCL17/TARC and CCL22/MDC. The activity of this receptor is mediated by G(i) proteins which activate a phosphatidylinositol-calcium second messenger system. Can function as a chemoattractant homing receptor on circulating memory lymphocytes and as a coreceptor for some primary HIV-2 isolates. In the CNS, could mediate hippocampal-neuron survival.
Predominantly expressed in the thymus, in peripheral blood leukocytes, including T-cells, mostly CD4+ cells, and basophils, and in platelets; at lower levels, in the spleen and in monocytes. Detected also in macrophages, IL-2-activated natural killer cells and skin-homing memory T-cells, mostly the ones expressing the cutaneous lymphocyte antigen (CLA). Expressed in brain microvascular and coronary artery endothelial cells.
Belongs to the G-protein coupled receptor 1 family.
In natural killer cells, CCL22 binding induces phosphorylation on yet undefined Ser/Thr residues, most probably by beta-adrenergic receptor kinases 1 and 2.
Spectral Confocal Microscopy of CHO cells using ab59550 at 1 µg/106 cells . CHO cells were transiently transfected with an expression vector encoding CCR4. Binding of ab59550 was visualized with a FITC-conjugated secondary antibody (green). Actin filaments are labeled with Alexa Fluor-555 Phalloidin (red). Cell nuclei are stained with DAPI (blue).
Flow Cytometry - CCR4 antibody [KH-4F5] (ab59550)
FACS analysis of BOSC23 cells using ab59550 at 1.2 µg/ 106 cells. BOSC23 cells were transiently transfected with an expression vector encodingeither CCR4 (red curve) or an irrelevant protein(control transfectant). Binding of ab59550 was detected with a PE conjugated secondary antibody.
