CTACK Recombinant Protein

CTACK is a keratinocyte-derived CC chemokine which signals through the CCR10 receptor. Both CTACK and CCR10 are expressed in normal and irritated epithelial cells. CTACK selectively attracts CLA+ T-cells and directs them into the skin. CTACK contains the four highly conserved cysteine residues present in most CC chemokines. The mature protein contains 88 amino acid residues. Recombinant murine CTACK is a 10.9 kDa protein containing 95 amino acid residues.

The lyophilized CTACK recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted CTACK is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing CTACK recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
