- Format
- Lyophilized
- Reconstitution
- We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
- Buffer
- Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.
- Handling Advice
- Avoid repeated freeze/thaw cycles.
- Storage
- 4 °C/-20 °C
- Storage Comment
- This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C.

- Background
-
The Trefoil Factor peptides (TFF1, TFF2 and TFF3) are secreted in the gastrointestinal tract, and appear to play an important role in intestinal mucosal defense and repair. TFF-3 is expressed by goblet cells and in the uterus, and has also been shown to express in certain cancers, including colorectal, hepatocellular, and in biliary tumors. TFF3 may be useful as a molecular marker for certain types of cancer, but its role, if any, in tumorigenesis is unknown. TFF3 also promotes airway epithelial cell migration and differentiation.
Synonyms: Trefoil Factor 3 Human, TFF3 Human - Molecular Weight
- 6.6 kDa, a single non-glycosylated polypeptide chain containing 59 amino acids, which includes a 40-amino acid trefoil motif containing three conserved intramolecular disulfide bonds.
