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 \u0026lt;-20°C. Further dilutions should be made in appropriate buffered solutions.\u003c\/p\u003e\n\n\u003cp\u003eStorage: 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. Avoid repeated freeze\/thaw cycles.\u003c\/p\u003e\n\n\u003cp\u003eUsage: This material is offered by USA Bioworld biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. Made in China\u003c\/p\u003e\n\n\u003cp\u003eDescription: 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.\u003c\/p\u003e","brand":"BioWorld","offers":[{"title":"5µg","offer_id":42882225537203,"sku":"PR1042-5","price":260.23,"currency_code":"CAD","in_stock":true},{"title":"20µg","offer_id":42882225569971,"sku":"PR1042-20","price":490.83,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/products\/thumbnail_d1447bac803ec9be_11-14-09-19-51_4a8aed53-f0de-4577-b5b4-6217fdb82cfe.jpg?v=1702049617","url":"https:\/\/afsbio.com\/products\/recombinant-human-human-trefoil-factor-3-rhutff-3-pr1042","provider":"AFSBio Inc.","version":"1.0","type":"link"}
