High affinity receptor for the C-C type chemokines CCL17/TARC, CCL22/MDC and CKLF isoform 1/CKLF1. 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.

①Measured by its binding ability in a functional ELISA. Immobilized Human CCR4 at 5 μg/mL can bind Anti-CCR4 recombinant antibody (CSB-RA004843MA01HU) . The EC50 is 2.803-3.369 ng/mL. ②Human CCR4 Full Length Protein captured on CM5 chip can bind Human CCR4 Monoclonal Antibody (CSB-RA004843MA01HU) with an affinity constant of 3.16 nM as detected by SPR Assay (Biacore T200) . ③Human CCR4 Monoclonal Antibody (CSB-RA004843MA01HU) captured on Protein A Chip can bind Human CCR4 Full Length Protein with an affinity constant of 1.71 nM as detected by MetaSPR Assay (in presence of FOS-12) (WeSPRTM200) .

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Chemokine-like factor 1 is a functional ligand for CC chemokine receptor 4 (CCR4) . Wang Y., Zhang Y., Yang X., Han W., Liu Y., Xu Q., Zhao R., Di C., Song Q., Ma D. Life Sci. 78:614-621 (2006)

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
