Synonyms | C-C motif chemokine 17, Small-inducible cytokine A17, Thymus and activation-regulated chemokine, CC chemokine TARC, ABCD-2, CCL17, CCL-17, SCYA17, TARC, A-152E5.3, MGC138271, MGC138273. | ||
Introduction | TARC cDNA encodes a 94 amino acid precursor protein with a 23 amino acid residue signal peptide that is cleaved off to generate the 71 amino acid residue mature secreted protein. Along with CC chemokine family members, CCL-17 has approximay 24-29% amino acid sequence identity with RANTES, MIP-1?, MIP-1?, MCP-1, MCP-2, MCP-3 and I-309. TARC is expressed in thymus, and at a lower level in the lung, colon, and small intestine. TARC is in addition transiently expressed in stimulated peripheral blood mononuclear cells. Recombinant TARC has been shown to be chemotactic for T cell lines but not monocytes or neutrophils. CCL-17 was recently identified to be a specific functional ligand for CCR4, a receptor that is selectively expressed on T cells. CCL17 is one of quite a few Cys-Cys (CC) cytokine genes clustered on the q arm of chromosome 16. CCL17 shows chemotactic activity for T lymphocytes, but not monocytes or granulocytes. CCL17 binds to chemokine receptors CCR4 and CCR8. This chemokine plays important roles in T cell development in thymus as well as in trafficking and activation of mature T cells. | ||
Description | CCL17 Human Recombinant produced in E.Coli is a single,non-glycosylated, polypeptide chain containing 71 amino acids and having a molecular mass of 8 kDa. The TARC is purified by proprietary chromatographic techniques. | ||
Source | Escherichia Coli. | ||
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | ||
Formulation | The protein was lyophilized from a concentrated (0.5mg/ml) solution containing 20mM PBS & 150mM NaCl pH-7.4. | ||
Solubility | It is recommended to reconstitute the lyophilized CCL17 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. | ||
Stability | Lyophilized TARC although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TARC should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles. | ||
Biological Activity | Determined by its ability to chemoattract human T-Lymphocytes using a concentration range of 1.0-10.0 ng/ml corresponding to a Specific Activity of 100,000-1,000,000IU/mg. | ||
Purity | Greater than 97.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. | ||
Amino acid sequence | ARGTNVGRECCLEYFKGAIPLRKLKTWYQTSEDCSRD AIVFVTVQGRAICSDPNNK RVKNAVKYLQSLERS. | ||
