Endotoxin level is < 0.1 ng/ug of protein (< 1 EU/ug).
Determined by its ability to chemoattract human T cells using a concentration range of 10.0-100.0 ng/ml.
Activity assay SDS-PAGE The optimal working dilution should be determined by the end user.
Lyophilized from solutions contain no sodiun azide nor carrier protein.
Store at -20°C. Reconstitute in water to a concentration of 0.1-1.0 mg/mL. Do not vortex. For extended storage, it is recommended to further dilute in buffer containing carrier protein (e.g. 0.1% BSA) and store in aliquots at -20°C to -80°C is recommended.
This gene is one of several Cys-Cys (CC) cytokine genes clustered on the q arm of chromosome 16. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. The cytokine encoded by this gene displays chemotactic activity for monocytes, dendritic cells, natural killer cells and for chronically activated T lymphocytes. It also displays a mild activity for primary activated T lymphocytes and has no chemoattractant activity for neutrophils, eosinophils and resting T lymphocytes. The product of this gene binds to chemokine receptor CCR4. This chemokine may play a role in the trafficking of activated T lymphocytes to inflammatory sites and other aspects of activated T lymphocyte physiology. [provided by RefSeq
