CCR4 (CC chemokine receptor 4) molecule belongs to the rhodopsin family of G-protein coupled receptors. Chemokine receptors are membrane bound molecules composed of 7-transmembrane domains and coupled to G-proteins. CCR4 binds the chemokines CCL17 (TARC) and CCL22 (MDC) and is highly expressed in most single-positive CD4(+) thymocytes especially in TH2- and regulatory T-cells. It plays a central role in T cell migration to the thymus, T cell maturation and education. CCR4 is often up-regulated in inflammation and cause conformational changes that trigger intracellular signaling pathways.
Suitable for use in ELISA, Flow Cytometry. Other applications not tested.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
