Anti-CCR4 (Chemokine Receptor 4, CC-CCR-4)

Chemokine receptors are specialized proteins that function at the surface of cells, and enable chemokines to trigger internal cellular processes. Chemokines and their receptors play a pivotal role in lymphocyte trafficking, recruiting and recirculation. Chemokines act through seven transmembrane G protein-coupled receptors. The chemokine system is increasingly recognized to play an important role in lymphocyte biology. CCR4 is a chemokine receptor and is preferentially expressed on type 2 helper T (Th2-type) cells. In contrast to other chemokine receptors, the expression of CCR4 and CCR8 on Th2 cells is transiently increased following TCR and CD28 engagement. Moreover, activated Th1 cells up-regulate CCR4 expression and functional responsiveness to thymus- and activation-regulated chemokine. , Applications: , Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1-2ug/ml In Daudi cell lysate, a band at 42kD should be detected. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C. Aliquots are stable for at least 12 months at -20°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.
