Product Overview | |
| Name | TFF2 Human, His |
|---|---|
| Description | |
| Trefoil Factor-2 Human Recombinant, His Tag | |
| Accession (Primary) | Q03403 |
| Synonyms | |
| TFF-3, ITF, TFI, HITF, hP1.B, TFF3, Trefoil factor 3, Intestinal trefoil factor. | |
| Introduction | |
| Proteins of the TFF family are characterized by obtaining a minimum of 1 copy of the trefoil motif, a 40-amino acid domain that contains 3 conserved disulfides. Trefoil Factors are stable secretory proteins expressed in gastrointestinal mucosa which protect the mucosa from insults, stabilize the mucus layer and affect healing of the epithelium.TFF2 inhibits gastric acid motility & secretion. TFF2 stabilizes glycoproteins in the mucus gel through interactions with carbohydrate side chains. TFF3 induces ciliogenesis and promotes airway epithelial ciliated cell differentiation, relatively through an epidermal growth factor receptor-dependent pathway. TFF3 overexpression is crucial for progression in mouse and human hepatocellular carcinogenesis. TFF-3 is normally expressed in hepatocellular carcinoma and its expression associates with tumor grade. | |

| Escherichia Coli. | |
| Physical Appearance | |
| Sterile Filtered White lyophilized (freeze-dried) powder. | |
| Formulation | |
| Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4. | |
| Stability | |
| Lyophilized TFF3 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution TFF3 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. | |
| Purity | |
| Greater than 97.0% as determined by RP-HPLC and SDS-PAGE analysis. | |

| EEYVGLSANQ CAVPAKDRVD CGYPHVTPKE CNNRGCCFDS RIPGVPWCFK PLQEAECTF. | |
| Biological Activity | |
| The ED50 as determined by a chemotaxis bioassay using human MCF-7 cells is less than 10 µg/ml, corresponding to a specific activity of > 100IU/mg. | |
| Solubility | |
| It is recommended to reconstitute the lyophilized TFF3 in sterile 18M-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. | |
| Precautions | |
| TFF2 Human, His is for research use only and not for use in diagnostic or therapeutic procedures. | |
