Found in the gastrointestinal tract, the three Trefoil proteins, TFF1, 2, and 3 have been shown to play an important role in intestinal mucosal defence and repair. Specifically, TFF1 is essential for normal differentiation of the antral and pyloric gastric mucosa and functions as a gastric-specific tumor suppressor gene.
Aliases- TFF1, Breast cancer estrogen-inducible protein, BCEI, PNR-2, Polypeptide P1.A, Protein pS2
- Recombinant Human Trefoil Factor 1 (TFF1)
Formulation- Lyophilized from a 0.2 µm filtered solution in PBS
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles.
