MDC Human

Macrophage-Derived Chemokine Human Recombinant (CCL22)

MDC Human Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 69 amino acids and having a molecular mass of 8.1 kDa.
The MDC is purified by proprietary chromatographic techniques.

Accession

O00626

Amino acid sequence

GPYGANMEDS VCCRDYVRYR LPLRVVKHFY WTSDSCPRPG VVLLTFRDKE ICADPRVPWV KMILNKLSQ.

Biological Activity

Determined by its ability to chemoattract human T cells using a concentration range of 10ng-100ng/ml corresponding to a Specific Activity of 1,000-10,000IU/mg.

Formulation

CCL22 filtered (0.4um) and lyophilized from a concentrated solution containing 20mM phosphate buffer & 500mM NaCl pH-7.4.

Physical Appearance

Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 97.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized CCL22 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

Source

Escherichia Coli.

Stability

Lyophilized CCL22 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution CCL22 should be stored at 4oC between 2-7 days and for future use below
-18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
