DATA SHEET :recombinant Human CTAC

-Human CTAC (Cuteaneous T-Cell Attracting Chemokine) is also known as Skinkine, Eskine and CCL27. CTAC is predominantly expressed in the skin and selectively attracts skin-associated memory T-lymphocytes. Recombinant Human CTAC is a 9.8 kDa protein containing 86 amino acid residues.

Catalog#: RDI-3054

Package Size: 20 micrograms $231.00   $219.00/pack 2+

                    Mini-Pack: cat#RDI-3054p $94.00/5ug

Supplied: Lyophilized powder with no additives.

Source: E. Coli

Purity: >98% by SDS-Page analysis. Endotoxin level is less than 0.1ng per ug (1EU/ug) of protein

Reconstitution: Lyophilized CTAC should be reconstituted in water to a concentration of 0.1-1mg/ml. Allow to set at least 30 minutes at 4 DEG C, mix well. If desired, tighten cap and centrifuge for 1 minute at 1000rpm to concentrate material in vial. This solution can be diluted into other buffered solutions or stored at 4 DEG C for up to 1 week or at -20 DEG C for future use.

-Note:If this material is not to be used for coating or labeling (or other applications requiring carrier free material), the addition of 0.1% BSA or HSA to dilution buffers or dilution in sterile culture media is recommended to enhance stability and minimize absorption to vial. Ideally, maintain stock >20ug/ml.

Storage: The lyophilized powder is stable at room temperature for a few weeks but it is best stored desiccated at -20 DEG C. Reconstituted CTAC should be stored in working aliquots at -20 DEG C. AVOID FREQUENT FREEZE THAW CYCLES.

Reactivity: Determined by its ability to chemoattract CXCR3 transfected cells using a concentration of 10.0-100.0ng/ml

Precautions: For In vitro research Use Only. Not for use in or on humans or animals or for diagnostics. It is the responsibility of the user to comply with all local/state and Federal rules in the use of this product. We are not responsible for any patent infringements that might result with the use of or derivation of this product.
