TARC, a CC chemokine, is predominantly produced by dendritic cells in the thymus and signals through the CCR4 receptor. TARC is chemotactic towards T cells. Recombinant human TARC is an 8.0 kDa protein containing 71 amino acid residues, including the four conserved cysteine residues present in CC chemokines.
Human CCL17 expressed in E.coli
CAT# CSC-CTK0588-20 (20 μg); CAT# CSC-CTK0588-100 (100 μg)
Greater than 99% as determined by SDS-PAGE and HPLC analysis.
Determined by its ability to chemoattract human T cells using a concentration range of 1.0-10.0 ng/ml.
Less than 1 EU/μg.
Lyophilized from a sterile-filtered solution in 0.3x PBS.
Please centrifuge product briefly before opening the vial. Reconstitute in sterile, ultra-pure water to a concentration of 0.1-1.0 mg/ml. This solution can be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized powder, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted TARC should be used immediately or stored in undiluted working aliquots at -20°C. Avoid repeated freeze / thaw cycles.
