		Technical Data
T2275-15	TECK, Recombinant, Human (Thymus-expressed Chemokine)	20ug

Growth Factors, Cytokines

Storage: -20°CShipping: Blue Ice

Source:
Recombinant corresponding to 127aa from human TECK expressed in E. coli.

Molecular Weight:
~14.2kD

Biological Activity:
The biological activity of TECK was determined by measuring its ability to chemoattract human monocytes. A concentration range of 1.0-10ng/ml produced significant chemotaxis. TECK is a member of the b chemokine (C-C) family, identified in the thymus of mice and humans. TECK is a chemoattractant for activated macrophages, dendritic cells and thymocytes. The receptor for TECK is CCR-9.

Endotoxin: ~0.1ng/ug
