Uniprot ACC number: O15444
Transportation method: Shipped at room temperature.
Stability: Lyophilized TECK although stable at room temperature.erature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TECK 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 (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Biological Activity: Determined by its ability to chemoattract human monocytes using a concentration range of 1-10 ng/ml corresponding to a Specific Activity of 100,000-1,000,000 IU/mg.
Solubility: It is recommended to reconstitute the lyophilized TECK in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
