Formulation

The TFF2 protein was lyophilized from 0.4um filtered solution at a concentration of 0.5mg/ml containing 20mM Tris pH-7.5, and 20mM NaCl.

Physical Appearance

Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 95.0% as determined by SDS-PAGE.

Solubility

It is recommended to add deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.

Source

Escherichia Coli.

Stability

Lyophilized TFF2 although stable at room temperature for 3 weeks, should be stored desiccated below -18oC. Upon reconstitution TFF2 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.
