Recombinant Mouse CTACK/CCL27

Description

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.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

> 98% by SDS-PAGE and HPLC analyses.

Biological Activity

Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human peripheral blood lymphocytes is in a concentration range of 10-100 ng/ml.

Endotoxin

<1 EU/μg of protein as determined by LAL method.

Formulation

Lyophilized from a 0.2 µm filtered concentrated solution in 2 × PBS, pH 7.4, with 5% trehalose.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20°C. Further dilutions should be made in appropriate buffered solutions.
