MDC is a small cytokine that belongs to the CC chemokine family. CCL22 is one of several Cys-Cys cytokine genes clustered on the q arm of chromosome 16. MDC shows chemotactic activity for natural killer cells, chronically activated T lymphocytes, monocytes and dendritic cells. On the other hand, MDC shows a mild activity for primary activated T lymphocytes and has no chemoattractant activity for neutrophils, eosinophils and resting T lymphocytes. MDC may also have a role in the trafficking of activated T lymphocytes to inflammatory sites and other aspects of activated T lymphocyte physiology. MDC interacts with cell surface chemokine receptors CCR4. CCL22 is vastly expressed in macrophage and in monocyte-derived dendritic cells, and thymus. CCL22 is also found in the lymph node, appendix, activated monocytes, resting and activated macrophages. Lower expression of CCL22 can be seen in the lung and the spleen and very weak expression in the small intestine. In the lymph
MDC是属于CC趋化因子家族的小细胞因子。 CCL22 是聚集在 16 号染色体 q 臂上的几个 Cys-Cys 细胞因子基因之一。MDC 显示出对自然杀伤细胞、慢性活化的 T 淋巴细胞、单核细胞和树突细胞的趋化活性。 另一方面,MDC 对原代活化的 T 淋巴细胞表现出温和的活性,对中性粒细胞、嗜酸性粒细胞和静息 T 淋巴细胞没有趋化活性。 MDC 还可能在活化 T 淋巴细胞向炎症部位的运输和活化 T 淋巴细胞生理学的其他方面发挥作用。 MDC 与细胞表面趋化因子受体 CCR4 相互作用。 CCL22 在巨噬细胞和单核细胞衍生的树突细胞和胸腺中大量表达。 CCL22 也存在于淋巴结、阑尾、活化的单核细胞、静息和活化的巨噬细胞中。 CCL22在肺和脾中的表达较低,在小肠中表达非常弱。 在淋巴


CCL22 Mouse Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 68 amino acids and having a molecular mass of 7.8kDa. The Mouse CCL22 is purified by proprietary chromatographic techniques.


Escherichia Coli.

Physical Appearance

Filtered White lyophilized powder.


CCL22 filtered and lyophilized from a concentrated solution containing 20mM phosphate buffer & 150mM NaCl pH-7.4.


It is recommended to reconstitute the lyophilized CCL22 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
建议在不低于 100µg/ml 的无菌 18MΩ-cm H2O 中复溶冻干的 CCL22,然后可以进一步稀释成其他水溶液。


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

Biological Activity

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


Greater than 97.0% as determined by: Analysis by RP-HPLC. Analysis by -PAGE.
