Biological Activity

Determined by its ability to chemoattract human MCF-7 cells using a concentration 1.0-10.0 ng/ml.

Formulation

Lyophilized from a 0.2um filtered concentrated solution in PBS, pH 7.4.

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 97.0% as determined by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized TFF3 in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized TFF3 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution TFF3 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.
